MACROCERAMUS, HAITI. 123 



radial stripes of dark brown and tawny ; interior of umbilical 

 area dark brown ; apical whorls varying from corneous-brown 

 to blue-black. Surface glossy, very closely and finely striate 

 on the upper half, the later whorls smoother or merely marked 

 with growth-lines, the base generally finely striate. Whorls 

 about 12, slightly convex, the last well rounded, often weakly 

 angular at the periphery. Aperture vertical, obliquely oblong, 

 the lip thin, narrowly expanded, the outer lip a little retracted 

 above, columellar margin dilated and reflected. Length 17- 

 19, diam. 7 mm. 



Haiti : coast of the cul-de-sac, at Gonaives (Richaud, Rolle), 

 St. Marc (Henderson & Simpson), Port-au-Prince (J. J. 

 Brown).

Variation is chiefly in the intensity of the numerous brown 

 spiral lines, which may be continuous and strong, or inter- 

 rupted between the oblique streaks, and weak, as in numerous 

 specimens before me from Port-au-Prince. Some of the shells 

 from St. Marc are ochre-yellow between the radial streaks of 

 the base. A variety was proposed by Weinland, based upon 

 Port-au-Prince shells collected by Dr. J. J. Brown ; but hav- 

 ing examined forty shells from the same place and collector, 

 it seems to me that they are typical lineatus, though many of 

 them are rather pale. The name guildingi, given by Petit (pi. 

 23, f . 55, copy of original figure) , is an absolute synonym of 

 the species excellently described by Bruguiere.
