Fusinus haitensis (Sowerby) 



Fusus haitensis Sowerby, Q. J. Geol. Soc, vi. 1849, p. 47. 

 Fusus henekeni var. haitensis Guppy, Q. J. Geol. Soc, xxii, pp. 524, 532, pi. 

 28, fig. 2. 



One broken specimen and two young ones with subangular whorls 



are referred to this species. Without more material we cannot say 



whether it is distinct from F. henekeni or a variety thereof.

Fusus henekeni Guppy, Q. J. Geol Soc. xxxii, 1876, p. 524, pi. 28, fig. 6. 



The figure given by Guppy is poor; the whorls should be more 

 convex, and the spiral ridges larger and less numerous, there being 

 only six or seven visible an the whorls of the spire. Many of the 

 specimens show alternating spiral ridges on the larger whorls. 

 Sowerby does not mention this character, but as Guppy 's figure 

 shows it indistinctly, we would consider the form with alternating 

 sculpture to be typical. 



It probably represents the ancestral form of F. eucosmius Dall, 

 now living in 27-73 fathoms in the Gulf of Mexico and West Indies. 



Length of the form with subequal spirals 71, diam. 22 mm. A 

 specimen with prominent alternating spirals on the two large whorls 

 (obsolete on the next earlier) measures length 89, diam. 26 mm. 



It appears to be an abundant species. 



Melongena (?). antillarum (Gabb) Plate XXVIII, figs. 10, 17. 



Heniifusus antillarum Gabb, Tr. Am. Philos. Soc. xv, 1873, p. 204. 



The largest cotype (fig. 17) has lost all of the spire, the last whorl 

 measuring, length 79, diam. 49.5 mm., aperture 63 mm. There is 

 a small ridge in the position of the inferior spine-series of the recent 

 Gulf species of Melongena. The strongly lirate interior is a prom- 

 inent feature. The smaller cotype (fig. 10) is a j'^oung shell 43.6 

 mm. long. 



A fragment of the canal indicates a size somewhat exceeding the 

 larger specimen. Two cotypes, with an additional fragment, no.

Very closely related to M. melongena, but differing by having 



strong spiral striation in the adult stage. It is also more ponderous. 



The height of the spire varies a good deal. The variations in the
