142 MACROCERAMUS, CUBA. 



24. M. PUPOIDES Pfeiffer. PL 20, figs. 13, 14. 



Shell deeply rimate, pupiform, the spire being somewhat 

 thickened, with convex outlines; solid; blue-white with a 

 series of blackish spots at the periphery and above the suture, 

 and often with a few faint brown streaks. Surface glossy, 

 finely, very closely and regularly striate, varying to nearly 

 smooth on the later whorls. 7 to 8 whorls remain, the earlier 

 ones being lost; they are convex, the last well rounded, not 

 keeled or only faintly so. Suture finely and regularly cren- 

 ulate, usually with a cream- white border below. Aperture 

 small, rounded; peristome thin, whitish, very narrowly ex- 

 panded; parietal callous thin. 



Length 14, diam. 5.6 mm. 



Length 12.5, diam. 5 mm. 



Eastern Cuba: Hacienda San Antonio, on the road from 

 Guantanamo to Baracoa (Wright, type loc.) ; Imias, district 

 of Baracoa (Arango).

A larger shell than the closely related M. jeannereti, with 

 the spire more robust The synonymous M. poeyi Pfr. (pi. 

 21, figs. 5, 6, 30, 31, 32), from the type locality of pupoides, 

 is merely a form in which the striae are obsolete on the later 

 whorls, while typical pupoides is closely striate throughout. 

 This is a trivial variation, common to most of the related 

 species, and it is evident from the lots before me from 

 Wright, Gundlach and Arango, that the smoothish and striate 

 shells occur together. 



25. M. JEANNERETI ' Gundl.' Pfr. PL 21, figs. 13, 14. 



Shell rimate, oblong-turrite, solid, regularly rib-striate, 

 the last whorl often smoother. Whitish or blue-white, with 

 a series of black-brown spots at the periphery and above the 

 suture on the last two or three whorls; usually reddish- 

 brown or purplish near the truncate apex, on the second
