GUPPYA. 123 
G. gundlachi appears to be widely distributed in the Antilles and on the continent 
of Central America, and has, perhaps, been introduced with vegetables into some of 
these places. | 
The systematic position of this species is somewhat doubtful, as it bears a consider- 
able resemblance to the European Conulus fulvus; the radula, however, figured by 
Binney, agrees very well with that of Guppya trochulina (selenkat), figured by Strebel 
(see anted, p. 120), and the mucous-pore has been observed by R. Tate 1%. 
The spiral strie in G. gundlachi are only visible under a strong lens; they are 
very regular, deeply cut, and rather numerous, but not very close together. Similar 
strie are also present in Mr. A. Morelet’s specimens of G. fulvoidea, from Carmen 
Island. This circumstance gives some additional weight to Tryon’s } identification of 
a Nicaraguan shell with Pfeiffer’s G. gundlachi. 
10. Guppya orosciana, sp. n. (Tab. VI. fig. 20, 20 a-d.) 
Testa anguste perforata, depresse trochoides, tenuis, nitida, sub lente spiratim striata, lete fulva; anfr. 5, 
planiusculi, sat celeriter crescentes, ultimus ad peripheriam distincte angulatus, basi leviter convexus ; 
apertura lunata, peristomate simplice, margine basali leviter arcuato. 
Diam. maj. 22, min. 23, alt. 12 millim. 
Hab. *N. GuatemMata: Coban (coll. Morelet). 
Costa Rica: Calera de San Ramon (S. Orosco). 
Distinct from the preceding (G. gundlachi) by the whorls being really angulated. 
The spiral strie are nearly as in that species. The specimen from Coban, in Morelet’s 
collection, is somewhat smaller, 24 millim. in diameter, and of a paler yellow colour ; 
but in other respects it agrees with the Costa Rican type, from which our figure is 
taken. Named in honour of Sefior Secundino Orosco, who assisted Prof. H. Pittier in 
his exploration of Costa Rica. 
Several species of a somewhat similar form and size, but distinct by the opaque (not 
shining) surface of the shell, will be found below (p. 131) under Helix, subg. Acanthinula.

Helix spirulata, Pfr. P.Z.S. 1845, p. 129'; Monogr. Helic. Vivent. i. p. 37°; in Martini & 
Chemnitz, Syst. Conch.-Cab. ed. 2, Helix, i. p. 244. no. 220, t. 30. figg. 11-14°; Reeve, 
Conch. Icon. vii., Helix, t. 110. fig. 617 *.

Hab. W. Nicaraeua: Realejo, on trunks of trees (Cuming 1 ®). 
Although this species differs by the remarkably larger size and the less glossy 
appearance of the shell from all the preceding, yet the spiral sculpture and the general 
outline of the shell seem to bring it near @. gundlachi. 1 therefore place it here pro-
