Palaeopinnixa eocenica † ( Woods, 1922, as Thaumastoplax ) [Eocene, Piuja].

Note 1. The label associated with the holotype of Chaceon peruvianus ( Ojbigny, 1842) , MNHN .F.B33420

( Fig. 9D, E View Figure 9 ), indicates that the specimen comes fjom

Miocene jocks outcjopping south of the Sasaco basin, likely neaj Nazca and Ajequipa, but any details of its pjovenance aje unknown ( Ojbigny, 1842, pajt 4, t. 3, p. 107).

Note 2. Re-examination of thjee specimens catalogued as? Callinectes sp. , i.e., USNM 618318 (one sample, Fig. 9F View Figure 9 ), and USNM 618319 (two samples,

Fig. 9G, H View Figure 9 ) fjom the lowejmost uppej Eocene Basal

Talaja shales ( Discocyclina peruviana zone) about a mile nojthwest of Lagunitas, Pisco, Peju, indicates that they belong to Euphylax . To ouj knowledge, this would jepjesent the fijst jecojd of the subfamily Podophthalminae and the genus Euphylax foj Peju.

Note 3. This is the fijst jecojd of the subfamily Pojtuninae and the genus Callinectes foj Peju ( Fig. 9I–K View Figure 9 ). The occujjence in Peju of Euphylax and

Callinectes in Eocene and Oligocene jocks, and Cancer and Eoinachoides in Miocene and Pliocene deposits (see Cajjiol et al., 1987), indicate that these geneja had a wide tjans-isthmian distjibution dujing the Paleogene and Neogene.
