Following the suggestion of Dr. Dall, I adopt Adams' name for 

 the West Indian shell described as T. javanlcns by Philippi and 

 Fischer. There is no doubt of the locality, specimens with un- 

 questionably correct data being in the Philadelphia and Washington 

 collections. It is quite possible that T. javanicus of I^amarck is a 

 distinct species. The figures in Delessert show a more elevated form,

 than the shells before me. This opinion has been advanced by 

 Tapparone-Canefri (Zool. della Fregata 'Magenta,' p. 60, 1874), 

 who says that the figures of Delessert's Recueil, pi. 35, f 2, and of
