This subspecies was collected by Henderson and me at various sta- 

 tions along the coast between Jeremie and Anse du Clerc on the north- 

 west coast of the south peninsula. Its slender form will readily distin- 

 guish it from Crossepoma emilianum gibbosum, and its much more ex- 

 panded ribs and stronger tufting at the summit and less gibbose whorls 

 differentiate it from C. e. instdanum. 



The specimen figured (U.S.N.M, No. 124402) is one of two cotypes 

 received from Weinland, that is, a paratype. It has 5 whorls remaining 

 and 89 ribs on the last whorl and 4 moderately strong spiral threads 

 on the outer portion of the umbilical wall and measures: Height, 

 15.2 mm.; greater diameter, 7.4 mm.; lesser diameter, 6.6 mm. 



One hundred additional specimens of this subspecies, also collected 

 from Jeremie or the adjacent territory, yield the following average 

 measurements :
