size ; and a siiprapalatal tooth, well developed in all specimens 

 examined. Peristome ferruginous, expanded, very broad in 

 the eolumellar margin, the outer margin with a deep inflection 

 in the middle, and with three impressions behind, of which the 

 shortest is above, the longest below. Length 1.75 mm., diam. 

 1.05 mm., aperture 0.6x0.73 mm. {Aguayo & Jaiime). 



Cuba: "La Lisa", Havana, under dead leaves in damp, 

 shady places, collected by M. L. Jaume and A. Bierig. Holo- 

 type in Aguayo collection, paratypes in collections of Jaume, 

 the Academy of Natural Sciences of Philadelphia, Mus. Com- 

 parative Zoology, Harvard, and U. S. National Museum. 



Vertigo torrei Aguayo & Jaume, Univ. de la Habana 

 Memorias de la Sociedad Poey, Vol. 8, no. 1, p. 11, text-fig., 

 March 10, 1934. 



Aguayo and Jaume add that this species resembles V. ovata 

 Say in general appearance, but differs by the constantly 

 smaller size, the more expanded eolumellar margin of the 

 peristome, as well as by the number and form of the apertural 

 teeth. In V. ovata an infraparietal lamella is often found, 

 which appears in none of the examples of V. torrei observed. 

 In the latter a suprapalatal tooth is always present, this being 

 infrequent in V. ovata. V. neglecta Poey resembles our torrei 

 in size and proportions, but lacks parietal teeth, yet it is pos- 

 sible that it was described from an imperfect example which 

 had lost these teeth by wear. We were unable to find the type 

 of V. neglecta in the Academia de Ciencias de la Habana. 

 Probably it is lost. At present it appears that we have to con- 

 sider V. neglecta as unindentifiable. 



Vertigo gouldii hubrichti, n. subsp. PL 22, figs. 12, 13, 14. 



The shell is subcylindric, larger than V. nylanderi Sterki, 

 with a similar long and deep impression over the palatal folds. 

 The lower-palatal is deeply immersed. There is no angular 

 lamella. The basal fold is well developed. The intermediate 

 whorls are strongly, sharply striate as in other forms of 

 y. gouldii. It differs from V. g. paradoxa by the deep ex- 

 ternal impression over the palatal folds.
