140 MACROCERAMUS, CUBA. 



22. M. GUNDLACHI (Pfeiffer). PL 20, figs. 1, 2, 3. 



Shell rimate, oblong-turrite ; whitish, sparsely marked with 

 dark brown stripes, which are either continuous or inter- 

 rupted, or have two or three projections on the right side; a 

 narrow dark band usually revolving below the periphery. 

 Surface striate on the early whorls, becoming smoother or 

 smooth on the later ones, but the striae reappear on the base. 

 Suture finely crenulate on the upper part of the spire, or 

 sometimes throughout. Spire long, with straight lateral out- 

 lines. Whorls 11 in entire to 8 in some truncate specimens, 

 the first 21/2 smooth, globose and glossy, pale; next whorl 

 usually dark; last whorl globose, with a weak subperipheral 

 carina. Aperture small, brown within, the lip whitish, acute, 

 unexpanded ; columellar margin a little dilated. Axis slender 

 and straight. 



Length 14, diam. 4.8 mm.; length of aperture 4 mm. 



Length 15, diam. 5.66 mm. ; length of aperture 5 mm. (type). 



Eastern Cuba: Punta de San Juan de los Perros (type 

 loc.), Cayos de Cardenos and Guisa, in Bayamo district 

 (Gundl.) ; Holguin (Clerch).

In length it varies from 12 to 15 mm. ; and the fine costula- 

 tion may extend over all but the last whorl or be confined to 

 the upper ones only. It is less solid and calcareous than re- 

 lated Cuban species. If it occurred in Haiti, it would be 

 grouped with M. klatteanus. Pfeiffer's original is copied in 

 my fig. 1. 



Group of M. pupoides. 



Shell rimate, rather solid, opaque whitish, usually streaked 

 obliquely, or with a series of spots at the periphery and above 

 the suture; no dark band below the periphery or around the 

 umbilical region. Surface varying from ribbed to smooth- 

 ish, but the post-embryonic whorls are always rib-striate and
