THE NAUTILUS.

group. The tooth on the basal lip is much smaller than in 

 emarginata. 



Specimens have been in the collection of the Academy for 

 many years labeled " H. emarginata'?" One lot from Bland 

 has the query "can these be young emarginata?" on the label 

 — Another lot was in the Van Nostrand collection, two speci- 

 mens having been given to the Academy. The collector of these 

 shells is unknown. 



Other views of the specimens now figured were given in 

 Nautilus, vol. 28, April, 1915, pi. 6, figs. 2, 2a, when I first 

 recognized the form as new. 



Z. emarginata (pi. 7, fig. 7) was first found by Gundlach at 

 Caimanera, on Guantanamo Bay, only dead ones in this arid 

 place. Afterwards he collected it at Mayan". Mr. Ramsden 

 has sent it from the following localities: Boca de Jaibo, 1 mile 

 below confluence of Jaibo and Guantanamo rivers. Arroyo 

 Hondo, Los Caiios, Guantanamo, Vinculo de Guantanamo. 

 Colonia " Blanco, n 2 miles southeast of Guantanamo. Also a 

 dead shell from Caimanera, Gundlach' s original locality. Fossil 

 specimens were sent by Mr. Aman some years ago from a de- 

 posit of clay at Guamo, on the Rio Cauto. Specimens from all 

 of these localities have been examined by the winter. There is 

 not much variation except in the height of the spire.

 kindness of Dr. Charles W. Richmond, the well-known orni-
