THE NAUTILUS. 23 



diameter of shell ; lip teeth of aperture typical in position, but very 

 small, almost obsolete. Alt. 10, diam. 23 mm. 



Burnside, Ky. (James H. Ferris). Types No. 71,399 coll. A. N. 

 S. P. 



Macrooeramus texanus n. sp. 



Shell resembling M. Gossei of Jamaica, but constantly stouter, 

 decidedly less attenuated above. Sculpture of thread-like oblique 

 stria?, finer and closer; sutural crenulation more irregular on the 

 lower whorls, and disposed to be subobsolete. Whorls 9* to 10*. 



Alt. 10z, diam. of penultimate whorl 3J mm. 



Alt. 8f, diam. of penultimate whorl 3j 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 striae 

 (instead of one or two, as in Gossei) ; striation of the spire finer 

 than in M. texanus. Whorls 9 to 9. Alt. 7i 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 Beries 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 striae 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 striae simple at the sutures. 

 That figure, however, is probably incorrectly drawn. M. Gossei 

 var. arctispira Aric. from Utilla Island, Honduras, is apparently a 

 small race of M. concisus Morelet, a common species in Yucatan.
