 das, Monterosato. 



The types of Jeffreys and C. B. Adams have been compared, and are iden- 

 tical. E. arcuata Sovverby (in Reeve, 1866) is a synonym of E. major Sow- 

 erby (1834), which in turn is a synonym of Melanella Dufresnei Bowdich 

 (1822) and Phasianella inflexa Blainville (1825). It is a totally distinct and 

 very much larger species. 



Eulima elongata (Dautzenberg) Dall. 



Eulima curva var. elongata Bucquoy, Dollfuss, and Dautzenberg, Moll. Mar. de 



Roussillon, I. p. 21, pi. xxi. fig. 15. 

 Eulima distorla Verrill, Trans. Conn. Acad., V. p. 526, not of Philippi. 



Habitat. Barbados, 100 fms. Key Largo, Florida, in fine mossy alga? at 

 low water, rare, Hemphill. Off the Carolina coast, 22-63 fms., sand, bottom 

 temperature 73°. 5 to 75°. F., U. S. Fish Commission. Norway (Sars) to 

 the Mediterranean and Canary Islands. 



This form seems to retain its characters so faithfully, that I can see no 

 reason why it should not be considered as good a species as most others in the 

 genus. 



Subgenus LEIOSTRACA H. & A. Adams. 



I can see no reason why Leiostraca and Leiostracus should not exist simul- 

 taneously in nomenclature, any more than Cyprina and Cyprinus. To reject 

 these established names in favor of Subularia and Venilia, as has been pro- 

 posed, is contrary to the spirit of scientific nomenclature, and serves to retard 

 rather than advance science. If it be thought impracticable to adopt for 

 Melanella the arrangement above suggested, the name of Eulima must be 

 conserved for this group, and Leiostraca be abandoned. 



Eulima (Leiostraca) acuta Sowerby.
