Guppya angasi (p. 120). (Tab. XLIV. fig. 2.) | 
Hyalinia (Stenopus) .angasi, Tryon, Manual of Conch, (2) ii. p. 182, t. 54. fig. 17 (copied from 
Angas) (1886) *. 
To the locality given, add :— es 
Hab. [E. Costa Rica:] between Mokri and Ukatschka, Alta T alamanca (Pittier, Sept. 
1898). ae 
SW. Cosra Rica: Quebrada de Java, 900 metres, Cafias Gordas (Pittier). 
In renaming this species angasi (anted, p. 120) I was unaware of the fact that ~ 
had already been done by Tryon, and for the same reason, viz. that * guildingt 
was preoccupied. I figure a specimen which seems to belong to it, the one given by 
Angas not being very satisfactory. It is recognizable by the narrow whorls, and by the 
distinct keel of the last one.
