PUPOIDES. 251 



mens are not distinguishable from those of Cuba, and there 

 appear to be no differences between those of the three islands 

 mentioned. It is variable in form and degree of development 

 of the angular callus. Two from E. Oranjestad, Aruba, 

 measure : 



Length 3.6 mm., diam. 1.55 mm. 



Length 3.6 mm., diam. 1.8 mm. 



Probably Leucochila simoni Jousseaume from Caracas is 

 identical with P. m. nitidulus. The description and figure 

 show no differences (Pilsbry, Proc. A. N. S. Phila., 1924, 

 p. 61). 



No doubt it was this race which was formerly reported from 

 Curasao as typical marginatus, since the latter was not found 

 by Dr. Baker in the course of a thorough search of the island. 



Pupoides lardeus (Pfr.), Vol. XXVI, p. 126, has been re- 

 ported from the Salt Range by Annandale and Rao, Rec. Ind. 

 Mus., XXV, p. 393. 



Pupoides zanguebaricus (Taylor). PL 31, figs. 10, 11. 



Vol. XXVI, p. 134. This species has about the size of P. 

 senaariensis, but it is distinguished by the absence of an an- 

 gular nodule, though in some examples there is a slight thick- 

 ening there. 



Length 4.1, diam. above aperture 1.7, to edge of lip 1.9 mm. 



Length 3.4 mm., smallest seen. 



The figure is from a Zanzibar specimen from coll. Bryant 

 Walker. 



Pupoides bryantwalkeri new species. PI. 31, fig. 12. 



The shell is very slender, the diameter (measured above 

 aperture) contained 3*4 times in the length. Summit obtuse; 

 spire slowly tapering, the last two whorls of about equal diam- 

 eter. The whorls are convex, the median ones more so than 

 the earlier or last. Color cinnamon-buff. Surface not glossy, 

 nearly smooth, but with some weak growth-ripples. The aper- 

 ture is small, broadly ovate, the peristome white, expanded, 

 somewhat thickened; outer lip regularly arcuate throughout, 

 narrowed above. Parietal callus thin, bearing a large, noduli-
