PUPILLIDAE AND BELATED GROUPS. 207 



first lateral subequal ; other laterals smaller ; marginals broad 

 with numerous interstitials. This is very similar to the radula 

 of N. (Indopupa) moreleti (Brown) as figured by Steenberg 

 (1925) except for his abnormal inner laterals. The central 

 in these two and the next species is very different from that 

 in Lyropupa and Limhatipupa. 



Nesopupa (Nesopupilla) plicifera Ancey. 



Four ovoviviparous animals from Nuuanu, Oahu (Cooke: 

 ASP. 117149) lack male genitalia; one gives the radular for- 

 mula : 12 — 1 — (5 + 7) ; teeth as in preceding species. 



Nesopupa (Cocopupa) cocosensis (Dall). Plates 28, figs. 

 8, 9. 



The anatomy of specimens from Wafer Bay, Cocos Island, 

 collected by Dr. Pilsbry on the Gifford Pinchot Expedition, is 

 very similar to that of N. newcomhi and only differences will 

 be noted. 



Vagina (fig. 8) shorter and stouter. Penial retractor 

 scarcely branched although with both insertions. Radular 

 formula (fig. 9) : 16 — 1 — (9 + 7) with 106 rows; central 

 and lateral cusps shorter and more aculeate. 



The radula of this species looks more like that of Bothrio- 

 pupa, both in relative breadth of the lateral field and in cusp- 

 shape, than like that of the Hawaiian Nesopupae. Incident- 

 ally, Ochrodermella, from the same locality, belongs in the 

 Ferussaciinae (Achatinidae) and has anatomy similar to that 

 of NeosuhuUna from the Dutch West Indies. 



BoTHRiOPUPA tenuidens (C. B. Adams). Plate 27, figs, 9, 10. 



A specimen from foothills behind the reservoir for Port 

 Antonio, Jamaica, collected Aug. 21, 1933, has very small male 

 genitalia (fig. 10). The anatomy (ovoviviparous) is very 

 similar to that in Nesopupa and the generic status of the latter 

 must depend on its shell characters. 



Radular formula (fig. 9): 13 — 1 — (7 + 6); central and 

 first lateral subequal with slender mesocones and 2-4 ectoconal 

 accessories.
