49. ICHTHYOPHIS MONOCHKOUS (Blkr.). 



IchihyopMs monochrous, Blgr. Cat. Batr. Grad. &c. p. 91, pi. iv. 

 fig. 1 (1882). 



In April 1898 on different days I obtained two specimens from 

 under a stack o£ firewood near " Maxwell's Bungalow," in the Larut 

 Hills, Perak, elevation 3380 feet. 



1st. Number of circular folds about 313 ; length 208 mm. 



2nd. Number of circular folds about 309 ; length 167 mm. 



As in I. glutinosus, some of the circular folds either bifurcate or 

 converge into each other ; therefore the number, in counting the 

 same individual at difierent parts of its circumference, varies. 



CoMir (in life). Uniform purphsh black. Tentacles white. 

 Anal region and tip of tail pale pinkish. The eye appears as an 

 inconspicuous black speck (but turns whitish in spirits). 



Distribution. India (Sikhim, Western Ghauts, Surat, Malabar), 

 Malay Peninsula, Borneo, Java. 



Addenda. — Mr. A. L. Butler has recently obtained in the Malay 

 Peninsula examples of two species not included in this list — Rana 

 jerhoa from the Batu Caves, Selangor, and Nectes subasper from 

 Sungei Buloh : he also obtained in Kuala Sumpor a male Rana 

 macrodon, measuring " exactly nine inches " (2281 mm.) from snout 

 to vent.
