Alt. 4.75, diam. 2.6, alt. of mouth 1.3 mm. 



The type and one half-grown specimen were taken at Camp 39, 

 M. & M. R. R. 



This species differs from all South American Leptinarias by the 

 broad uml)ilicus and the sinuous outer lip. 

 Leptinaria imperforata n. sp. PI. XXI, fig. 19. 



Shell imperforate, oblong conic, thin, pellucid, glossy, waxy hyaline, 

 very delicately striulate except on the smooth 1| nepionic whorls; 

 striulae slightly arcuate, nearly vertical, but tending to become 

 retractive on the base; all except the embryonic whorls showing an 

 obsolete spiral striation under a glass; apex rather obtuse. Whorls 

 5, convex, the last on its posterior aspect exactly equalling half the 

 total length. Aperture irregularly oval; peristome unexpanded, 

 simple, curving broadly below the columellar extremity; columella 

 short, not reaching to the base, nearly straight and vertical, obliquely 

 truncate, the anterior portion twisted sharply inward, thus leaving 

 no trace of an umbilicus or umbilical fold. 



Alt. 4.6, diam. 2, length of aperture 1.6, diam. of aperture .85 mm. 

 One mature and two immature specimens were taken at Camp 39, 

 M. & M. R. R. 



The species is closely related to L. anomala Pfr., from which it 

 differs by lacking the columellar reflection and the umbilicus, and by 

 its more slender shape and slightly narrower aperture. 



FBRUSSAOID^. 



Genus CiECILIOIDES Ferussac. 



Caecilioides (Geostilbia) gundlachi (Pfeiffer).

Ccecilioides gundlachi (Pfr.), Pilsbry, Man. Conch., (2), XX, p. 43. 



Eight specimens were sent by Mr. Rocha, ''taken in my garden," 



in the city of Ceara. The species has been reported from the West 



Indies and Demerara, but not hitherto from Brazil. 



Genus SYNAPTERPES Pilsbry. 

 Synapterpes sp. undet. 



Four nepionic shells, probably of this genus and possibly new, but 

 too young for exact diagnosis, were sent by Mr. Rocha. They were 

 taken on the Maranguape Mountain near Ceara. 



PUPILLID^. 



Genus BIFIDARIA Sterti. 

 Bifidaria sevilis (Gould). 



Pupa servilis Gld., Bcston Journ. N. H., IV, p. .3.56, pi. 16, fig. 14.
