var. pscudospinosa (Nevill). 



1885. Melaiiia {Melanoidei) variabilis subsp. episcopalis var. psettdo- 

 spinosa, Nevill, op. cit., pp. 258, 259. 



As Nevill has pointed out this variety appears to be interme- 

 diate between Bret's M sumatrensis and M. spinnsa. The type- 

 specimens were from Assam, but Nevill found it hard to distinguish 

 some Perak and Malacca specimens f ro n them. I can find no 

 difference between the Sumatran shells I assign to this form and 

 those from Assam, Perak and Malacca. 



This variety leads on to the form menkeana (Lea), but differs 

 from the latter in the suture being less impressed, the spines much 

 smaller and less protruding, and the shell being much smaller. 



The Sumatran specimens were collected along with those of 

 the vars. infracostata and binodidifera.

Nevill fully discussed the confusion introduced by Brot and 

 by Hanle}- and Theobald (Conch. Indica) regarding this form. 

 He gave a full sj'nonymy and emended the description of the 

 species. The form, as stated already, is closely allied to the var. 

 pscudospinosa , but differs in colouration, in the whorls being more 

 convex, the suture sharply and more deeply impressed, and in the 

 spines being better developed. 



I can detect no differences between the Assamese and the 

 Sumatran specimens. 



All the Sumatran specimens are from the Soengei Lepan in 

 Langkat. The measurements (in millimetres) of a few specimens 

 are as follows : —

Genus Melanoides, Ohvier {nee H. and A. Adams). 



1920. Melanoides, .Annandale, Rec. Iiid. Mas. XIX, pp. lo8, 109. 

 In the paper cited above Annandale has given reasons for 

 accepting the generic name Melanoides for the species of the type 

 of M. tuberculata (Miiller), and not in the sense it was used by H. 

 and A. Adams. He has also given a complete synonymy of the 

 genus. My examination of the large Sumatran collection com- 

 pletely upholds his views, except that I adopt, for the sake of con- 

 venience, some of the subgeneric names used by von Martens for 

 the various groups of species.
