diameter of shell ; lip teeth of aperture typical in position, but very 
small, almost obsolete. Alt. 10, diam. 23 mm.

Macroceramus texanus n. sp. 
Shell resembling M. Gossei of Jamaica, but constantly stouter, 
decidedly less attenuated above. Sculpture of thread-like oblique 
strie, finer and closer; sutural crenulation more irregular on the 
lower whorls, and disposed to be subobsolete. Whorls 93 to 103. 
Alt. 103, diam. of penultimate whorl 33 mm. 
Alt. 83, diam. of penultimate whorl 33 mm. 
New Braunfels, Comal Co., Texas. 
Macroceramus floridanus n. sp. 
Shell resembling M. Gossei somewhat, but smaller, very much 
more finely and closely striated, the sutural denticles less pro- 
nounced, mainly formed by the confluence of three or several strize 
(instead of one or two, asin Gossei) ; striation of the spire finer 
than in VM. texanus. Whorls 9 to 9%. Alt. 73 to 8, diam. of penul- 
timate whorl 3 mm. 
Little Sarasota Bay, Florida. 
A comparison with good series of the true M. Gossei Pfr. from 
Jamaica, the type locality, with series from Florida and Texas, 
shows that there are certain readily observable differences. The 
Jamaican shell is more coarsely and distantly striated than any 
Continental specimens ; the denticles at the suture are formed by 
single striz or the confluence of two, and the shell is more con- 
spicuously variegated than the generality of Floridan or Texan 
specimens. If fig. 458 of the “ Manual of American Land Shells” 
was drawn from a Continental shell, or from the Jamaican M. 
Gossei, it is incorrect in showing all the striz simple at the sutures. 
That figure, however, is probably incorrectly drawn. M. Gossei 
var. arctispira Anc. from Utilla Island, Honduras, is apparently a 
small race of M. concisus Morelet, a common species in Yucatan.
