GASTROCOPTA, NORTH AMERICA, WEST INDIES. 



jamaicen-sis, which is exactly synonymous with Pfeiffer's 

 Cuban species. Kuester's figure is very poor and incorrect. 



Pupa ovum formicae (pi. 15, fig. 6). Shell very small, 

 rimate, cylindrical, under a lens delicately obliquely striatu- 

 late, buff-corneous, thin; spire with obtuse apex; suture a 

 little impressed; whorls 5, slightly convex, the last shorter; 

 aperture subquadrangular, with one compressed parietal 

 tooth, a wider one on the columella; peristome thickened, a 

 little expanded throughout. Length 1%, diam. % mm.

Pupa ovum formicae WEINLAND, Jahrbucher der Deutschen 

 Malak. Ges., vii, 1880, p. 377, fig. in text. Pupa myrmecoon 

 ROSSE, Journ. de Conchy!., xxix, 1891, p. 152. 



This and the preceding species [P. desiderata] are, so far 

 as we know, the first small Pup as of the group Pupilla Leach 

 to be made known from Haiti ; and the first belongs to the 

 abbreviatae (of von Martens), the second to the cylindricae. 

 All of these [other West Indian] species have either fewer or 

 more than two teeth, and each has besides other characteristic 

 features ( Weinland ) . 



Notwithstanding the alleged absence of basal and palatal 

 plicas in ovum formicae, I have very little doubt that it is 

 merely pellucidu in which the smaller teeth were present as 

 usual, but were not seen. Such oversight is not unusual in 

 the literature of Pupillidcc, incredible as it may appear. 



Considering ovum formicae objectionable as a name, Crosse 

 substituted myrmecoon; he had not seen the species. 



23. GASTROCOPTA LONGURIO (Crosse). PI. 15, fig. 8. 



Shell rimate, elongate, thin, marked with fine oblique 

 striae, inconspicuous and scarcely visible under a lens, sub- 

 translucent, corneous, shading into dirty white. Spire 

 lengthened, terminating in an obtuse summit. Suture not 

 strongly marked. Whorls 5, a little convex, the last shorter 

 than the spire. Aperture nearly round. Peristome subcir- 

 cular, almost continuous, shortly expanded and dirty white;
