A single $ example from JMatheran, received from Mr. H. M. Phip- 

 son. In tbe thickness of the hand and shortness of the digits this 

 species, as well as in tbe form of the vesicle, shortness of the aculeus, 

 etc., resembles /. hasilicus of Karsch from Ceylon ; but in the latter the 

 spine on the vesicle is not triangular but has a rounded edge ; the tail 

 too is much less coarsely granular, being almost smooth ; and the 

 superior keels of the 2nd and 3rd segments terminate posteriorly, 

 not in a slender upstauding spine, but in a low triangular 

 tubercle.
