7C394D6EE752FF8AC1F9E8E03B12F9CA.taxon	discussion	Remarks. The oscules of the collected specimen were rarely visible. Despite the species’ sciophilous preferences (Carballo 1994), MMF 35059 was found exposed to light.	en	Pestana, Rosa, Ribeiro, Cláudia, Boury-Esnault, Nicole, Biscoito, Manuel (2018): Systematic account of new Porifera (Demospongiae) records from the oceanic Island of Madeira (NE Atlantic).

7C394D6EE752FF8AC1F9EBCB3C83F875.taxon	discussion	Remarks. The specimens collected were in gamma stage, the biggest with 85.76 cm 2. One specimen was degraded. The spicules had some distinct aspects when compared to descriptions in the literature: tylostyles’ heads were slightly larger than the usual; few tylostyles with heads slightly trilobed, with a small swelling; some tylostyles have an incipient second tyle below the head, resembling polytylotes; and in all spicules, an axial canal is visible.	en	Pestana, Rosa, Ribeiro, Cláudia, Boury-Esnault, Nicole, Biscoito, Manuel (2018): Systematic account of new Porifera (Demospongiae) records from the oceanic Island of Madeira (NE Atlantic).

MMF 35073 / Location: Baixa do Carneiro, Lido (BC), Madeira island / 7.5 m depth / Date: 3 apr 2001 and 4 m depth / Date: 18 jun 2001 / Collector: Rosa Pestana.	en	Pestana, Rosa, Ribeiro, Cláudia, Boury-Esnault, Nicole, Biscoito, Manuel (2018): Systematic account of new Porifera (Demospongiae) records from the oceanic Island of Madeira (NE Atlantic).

7C394D6EE751FF89C1F9EF123A5BFAFF.taxon	discussion	Remarks. In the Mediterranean this species grows more or less like a ramified small tree, while in the Atlantic as encrusting forms (Carballo 1994), as shown by the specimens collected in this survey. The spicules are composed by straight and thin subtylostyles (157.5 ‒ 325.4 ‒ 409.5 x 5.3 ‒ 5.3 ‒ 5.3 µm). Principal styles curved, and slightly constricted in one extremity (252.0 ‒ 425.1 ‒ 598.5 x 6.6 ‒ 7.9 ‒ 9.2 µm). Accessory styles, like principal styles, but smaller (152.2 ‒ 173.6 ‒ 241.5 x 5.3 ‒ 6.7 ‒ 7.9 µm). Toxas smooth with both extremities slightly curved (26.3 ‒ 93.9 ‒ 170.9 x 1.3 ‒ 1.7 ‒ 2.6 µm). The palmate isochelae (15.8 ‒ 16.4 ‒ 18.4 x 3.9 ‒ 5.1 ‒ 6.57 µm) found in the specimens were few. We don’t refuse the hypothesis that palmate isochelae could be cleistochelae, because no SEM was available. Occasionally, microscleres include palmate isochelae and modified forms, and toxas with smooth or spined points (Hooper 1996), yet those characters were not found in the collected specimens. MMF 35073 was compared with the literature (Van Soest et al. 2013), focusing on some specimens, and mainly those caught by Boury-Esnault and Lopes (1985) at Stations: Aç 79 - 16; Aç 79 - 17. We can hesitatingly conclude that MMF 35073 is like Clathria (Clathria) coralloides sensu Boury-Esnault and Lopes (1985) by the type and micrometries of spicules, and its encrusting habit. Possibly, in the future this specie can be assigned has C. (C.) arcifera com. nov. (Van Soest 2013). This species is distributed in Azores and Mediterranean, being this study the first record from the Central East Atlantic until Cape Verde (not included).	en	Pestana, Rosa, Ribeiro, Cláudia, Boury-Esnault, Nicole, Biscoito, Manuel (2018): Systematic account of new Porifera (Demospongiae) records from the oceanic Island of Madeira (NE Atlantic).

7C394D6EE751FF89C1F9EDB23944FE1C.taxon	discussion	Remarks. MMF 3507 has straight and very spiny acanthostyles with irregular bases (78.9 ‒ 118.0 ‒ 181.5 x 6.6 ‒ 8.2 ‒ 10.5 µm) and all have a head, occasionally only slightly evident. Subtylostyles (1542.0 ‒ 1781.2 ‒ 1946.0 x 11.8 ‒ 13.8 ‒ 15.8 µm) and tornote (343 ‒ 343 ‒ 343 x 1.7 ‒ 1.7 ‒ 1.7 µm) are rare. The specimen collected had accumulation of detritus over the body, and some subtylostyles showed specks in their heads, which we were unsure whether they were spines or detritus.	en	Pestana, Rosa, Ribeiro, Cláudia, Boury-Esnault, Nicole, Biscoito, Manuel (2018): Systematic account of new Porifera (Demospongiae) records from the oceanic Island of Madeira (NE Atlantic).

7C394D6EE751FF89C1F9E817393CF95F.taxon	discussion	Remarks. Although three types of anisochelae and two types of sigmas were described in the type specimen, only large anisochelae (31.6 ‒ 34 ‒ 39.5 x 2 ‒ 2 ‒ 2 µm) and large sigmas (81.5 ‒ 81.8 ‒ 81.8 x 3.4 ‒ 3.4 ‒ 3.4 µm) were found in our specimen. Tylostyles’ heads are slightly swollen. Despite the Mycalidae often includes several types of spicules, the extremely encrusting shape of the small specimen collected (1 mm thick) conditioned the procedure for OM slides. We also recognize that some spicules should be observed by SME, but that was not possible at the time of preparation and identification.	en	Pestana, Rosa, Ribeiro, Cláudia, Boury-Esnault, Nicole, Biscoito, Manuel (2018): Systematic account of new Porifera (Demospongiae) records from the oceanic Island of Madeira (NE Atlantic).

7C394D6EE751FF89C1F9EA773AC4F827.taxon	discussion	Remarks. Curved tylotes are rare but straight tylotes are characteristic (192.0 ‒ 215.0 ‒ 236.7 x 2.6 ‒ 3.4 ‒ 5.3 µm). Straight onychaetes (84.2 ‒ 118.8 ‒ 136.8 x 0.62 ‒ 0.74 ‒ 0.75 µm) and occasionally slightly curved. The specimen collected had mucus, and was found partially covered by algae.	en	Pestana, Rosa, Ribeiro, Cláudia, Boury-Esnault, Nicole, Biscoito, Manuel (2018): Systematic account of new Porifera (Demospongiae) records from the oceanic Island of Madeira (NE Atlantic).
