Occasional Papers of the Museum of Zoology 35 



Thesaurus. A set of specimens (A. X. S. P. 12990), labeled 

 Caracas. Venezuela (L 11, 67), are very similar in shape to 

 P. t. bcjuinciisis, but their considerably larger size seems to 

 indicate at least racial significance. They are labeled var. 

 Major in Thomas Bland's handwriting, so, with the kind 

 permission of Dr. Pilsbry, that name is published here (see 

 key, and fig. v-H). 



Poteria translucida santaguitensis, new subspecies 

 Figs. v-I. J. 



Four adults and 10 younger specimens, from root-humus 

 around bases of trees on the steep valley sides of Quebrada 

 Santa Aguita ( H, I, c, 42), near La Fria, Venezuela. 



Shell: heavier than P. f. translucida, and growth lines ren- 

 dered more prominent by fine, undulating, epidermal riblets. 

 Color of adults: olive-green, translucid. Apex: tinged with 

 rose. Last whorl : impressed just below suture, and often with 

 a few, weak, spiral striae. Basal lip of peristome : with a def- 

 inite emargination. as seems characteristic, of P. translucida. 

 Umbilicus: i j of the major diameter. 



The immature specimens of this subspecies are often vel- 

 lowish in color. In many respects, the adults resemble P. 

 sinitlii ( Pilsbrv and Clapp. Nautilus. 1902), as indicated in 

 the key. A l)leached specimen in the A. X. S. P. (no. 12993), 

 from Cucuta, Coloml)ia ( L. 8. /T)), probably also belongs to 

 P. t. santa(/uitc>isis. 



Poteria straminea (Reeve, 1843). Figs. v-X, O. 



Thirty adults and 48 immature specimens, from root-humus 

 on the hill-sides and around the bases of trees, in the San 

 Esteban valley (H. L c, 2, 3, 4).
