134 OLEACINA, HAITI. 



more rapidly descending. Outer lip obtuse, well arched for- 

 ward in the middle. Length 14, diam. 5.2, aperture 8 mm. ; 

 whorls 5 l /2- 



Haiti: St. Mark (Henderson and Simpson); Santo Do- 

 mingo (W. M. Gabb). 



This is probably the form reported by Weinland. 



4. O. PETHIONIS (Weinland). 



Vol. I, p. 23, pi. 11, fig. 83. This species is larger than 0. 

 smithiana, and distinguished especially by the conic, straight- 

 sided spire. Length 22, length of aperture 14 mm., whorls 7. 



Haiti: Port-au-Prince (Weinland). 



Glandina pethionis WEINL., Jahrb. D. M. Ges., vii, 1880, 

 p. 355, pi. 12, fig. 9. 



Named for the mulatto President Pethion. 



A mutilated specimen of a form evidently close to pethionis 

 was found by Mr. Henderson at Port-au-Prince. It has the 

 spire more slender than in Weinland 's figure, its sides 

 slightly concave, and the last whorl tapers more to the base. 

 It has somewhat the appearance of a high-spired Conus. The 

 sculpture is like that of 0. cleriei irregularly grooved, and 

 the aperture is quite narrow. It measures 17 x 6.5 mm., with 

 71/2 whorls. 



5. 0. CLERIEI (Weinland). PL 32, figs. 19, 23, 24, 25, 26. 

 Vol. I, p. 25. Specimens taken by Mr. Henderson at Jere- 



mie, the type locality, agree with Weinland 's brief descrip- 

 tion and his figures in general characters, but he does not 

 seem to have noticed the sculpture. 



The thin shell is yellow, with occasional darker olive-yellow 

 streaks. The spire is conic above, the outlines becoming 

 strongly convex below in adult shells. The first whorl is 

 smooth, enlarging very rapidly; the second whorl then be- 

 comes much narrower, and its last half is striate (fig. 19). 

 The following whorls enlarge at a rapidly increasing rate. 

 They have rather deep vertical grooves or furrows at irreg- 

 ular but rather close intervals. These grooves become less 

 deep and rarer on the last whorl in adult shells. The lip 

 curves rather strongly forward.
