Dall ^) is certainly wrong in assuming that the spécimens figured by Chemnitz and on 

 which Lamarck founded the species Mytihis cinnamomea must hâve been West Indian. The 

 Chemnitzian figures resemble very closely Indo-Pacific shells, and in view of Chemnitz first 

 discussing the shells of his species from the Spengler collection and which were from the Nicobar 

 Islands, there is every reason to refer his figures also to the Indo-Pacific species. I am not clear 

 why Dall considered Lithophaga [Bohcla) fttsca (Gmelin) to be definitely an East Indian species, 

 for Gmelin does not mention the provenance of this species, and his description is too brief to 

 enable this question to be settled with any certainty. I am unfortunately not in a position to 

 offer a definite opinion on the question of the East and West Indian forms being conspecific 

 or distinct, but I am inclined to gravely doubt such a wide distribution for a boring mollusc of 

 more or less sedentary habits, and unless the two forms are definitely shown as identical, would 

 much prefer to consider them as distinct. 



The "Siboga" spécimens, vi^hich I refer to the species, are ail rather young shells, and 

 were obtained in Sapeh Strait (St. 49 a), on the Bank between the Island of Bahuluwang and 

 Tambolungan, South of Saleyer (St. 66), at Pulu Sanguisiapo, Sulu Archipelago (.St. 93), the 

 Anchorage off North Ubian (St. 99), Anchorage near Seget, west entrance of Selee Strait 

 (St. 163) and Tuai Anchorage, Kei Islands (St. 258).
