146 Contributions to Indian Malacology. [No. 2, 
Unio spuria is said by Lamarck to be from Southern Asia. Mr. 
Benson states (Ann. and Mag. Nat. Hist. 1862, X., 189,) that the 
young of U. favidens approaches the figure given by Wood of Mya 
spuria, which is, I suppose, the same species. It is not clear that 
Lamarck’s type was Indian. Mr. Benson also (1. c. p. 189) refers to 
Mya radiata, Chem. as being from Malabar. Mya radiata, Gmelin is 
by Lamarck, Lea and Kiister, said to be American, and even in 
Kiister I can find no allusion to Chemnitz’s species. 
It is only right to add too that some of what Woodward most 
justly terms “the worthless fabrications of Rafinesque’” (Man. Mol. 
p. 136, note,) came from India. No scientific purpose can be served by 
recalling the names from the oblivion in which they are happily buried.

I only know of this and the succeeding three species from reference 
being made to them by Mr. Benson in the Ann. and Mag. Nat. Hist. 
for 1862, 3rd Ser. X., 186. The work in which they were originally 
described is not procurable in Calcutta. U-. involutus is said to be 
thin and tumid and to represent U. olivarius, Lea, in Assam.

Mr. Benson (in Ann. and Mag. Nat. Hist. 1862, X., 186) states 
that U. fluctiger, Lea, is a synonym of U. Scobina. Kiister’s figure 
of fluctiger differs from Lea’s type, and the shell is stated to be from 
S.America. As, however, Kiister’s specimen was from Dr. v. d. Busch’s 
cabinet, very little reliance can be placed upon the assigned locality, 
especially as Lea, who did not know whence the shell came, sug- 
gested that it was, possibly, South American,
