Animal very dark slate-color, almost black, oculiferous tentacles 

 long and slender, and, like the neck, finely granulate ; body ob- 

 liquely wrinkled ; foot and mouth paler, respiratory orifice very 

 large. 



This shell, with its thick green epidermis, looks like a Paludina, 

 especially like fresh specimens of P. decisa Say, which have similar 

 series of cilise. Another Brazilian species, B. velutinohispidus 

 Moric., has a similar velvety vesture, but it is a more globular, 

 heliciform species. (G7d.). 



The apical whorls are striolate as in B. scobinatus, but that is a 

 decidedly more slender species. B. velutinohispidus is more globose, 

 with different apical sculpture. As in B. scobinatus, the body-whorl 

 is indistinctly keeled peripherally at its origin, and the lip is very 

 narrowly expanded audsubreflexed. Gould's figures, which I have 

 copied on pi. 13, show the hairs too long. 



B. KOSERITZI (Clessin). 



Shell rounded-ovate, rather strong, openly umbilicated. Spire 

 short, conic ; whorls 7, slowing increasing, separated by sutures of 

 little depth, the last whorl fully half the entire length of the shell. 

 Surface of the whorls slightly striated, with (in the single decortica- 

 ted specimen before me) little shallow, irregularly placed depres- 

 sions, apparently indicating that fresh shells are hairy. Aperture 

 narrow, ovate, strongly attenuated above ; the peristome somewhat 

 thickened and expanded ; parietal callus thin. Columella nearly 

 straight. Alt. 20, diam. 14 mill. (Clessin).

Bulimus (Rhi)ius) koseritzi CLESS., Malak. Blatter (n. F.), x, p. 

 168 (1888?). 



Clessiu omits the locality, but it is probably either from Bahia or 

 southern Brazil near Taguara. The " unregelmassig angeordnete 

 Vertiefungen " are exceptional in Rhinus, the hairs or hair-scars 

 being arranged in spiral lines as a rule. The position of the species 

 is, therefore, uncertain.
