MELANIID^!. 251 



tinct, much as in typical M. gloriosa, but more crowded ; like 

 the typical form, it is throughout regularly, though indistinctly, 

 spirally striate. There are three specimens also in the collection 

 of Mr. H. F. Blanford, and on the same tablet, presumedly 

 from the same locality, " Henzada," a single specimen of M. 

 reevei. It is very interesting to find the two species living 

 together ; this occurrence is confirmed by the specimens from 

 Dr. Stoliczka's collection, wherein 1 found the two above-record- 

 ed specimens and a young M. reevei mixed together. 



var. beddomeana, nov. [? dist. sp.]. 



5 Near Moulmein ; coll. Colonel R. H. Beddome. 



An exceedingly interesting form. Long. 44, diam. 17| mil. ; 

 slightly decollate, of five whorls. Closely resembles the preceding 

 in shape of the whorls and spiral striation at base of last whorl ; 

 relatively even more solid ; appears to be perfectly smooth 

 throughout, with the exception of the above-mentioned basal 

 striation. 



39. Melania [Melanoides] herculaea. 



Melania herculaea, Gould, P. ost. 8.11,1846, Tavoy River; Con. Indie a, 

 pi, 72, fig. 5, and var. sowerlyi, Ranley, 1. c., pi. 109, jig. 7 ; var. M. 

 julieni, Brot. 



50 Near Moulmein [Tenasserim Prov.] ; coll. Baron P. von Richthofen 

 and Herr 0. Limborg. 



The largest long. 81^, diam. 33 mil. 



Prof. Brot apparently does not know this species, as he con- 

 fuses it with a mere local race of Mel. variabilis ; this he figures, 

 pi. X, fig. 1, as "typical" Mel. herculcea. On the same plate, 

 fig. b, he figures a young specimen of the true Mel. herculcea, 

 and remarks quite correctly that it is the M. hercucela, var. 

 sowerbyi, of the Con. Indica. Moreover, he redescribes, most 

 excellently, a local form of it as a new species M. julieni, Des- 

 hayes, MS., from Tonkin.
