conspicuously white." The crown and body too are darker tliaii in 

 P. prinmus. I cannot help suggesting that the so-called Presbytes 

 thersites was really a variety of S. cephalopterus, perhaps approach- 

 ing the variety called S. kelaarti by Schlegel '. 



V. On Semnopithecus pileatus and S. chrysogaster. 



Dr. J. Anderson, in his ' Anatomical and Zoological Researches ' 

 (p. 13), and again in his ' Catalogue of Mammalia in the Indian 

 Museum,' has classed these terms as synonymous, I think from havino- 

 misunderstood some remarks of Blyth's in the posthumous 'Catalogue 

 of the Mammals and Birds of Burma,' p. 1 1 ^ The two species 

 are really very different, not only in coloration, hut in structure, 

 for 5. pileatus has a peculiar cap of long harsh hair confined to the 

 crown of the head, of which there is no trace in S. chrysorjaster. 

 The latter however appears, judging by the only known adult 

 specimen, to have a compressed crest extending from the vertex to 

 the nape. 



Although an excellent figure of 8. chrysogaster was published bv 

 Professor Peters (MB. Akad. Berlin, 18/!), p. 830, pi. \v.b), no 

 description except Blyth's (Cat. Mamm. Birds Burma, I. c), taken 

 from the drawing, has ever appeared, so far as I am aware. The 

 animal might, however, easily be recognized from Blyth's account 

 which is good. ' 



It is marvellous that so beautiful a species as 5*. chrysoyaster 

 should never have been detected again, if this animal is really from 

 Tenasserim. It is true that the interior of Tenasserim, even to this 

 day, is almost uninhabited, and very rarely visited by Europeans, the 

 difliculties of travelling being excessive. But still it is remarkable 

 that amongst the collections made since the davs of Heifer by Major 

 Berdmore, Captain Beavan, Mr. Davison, Mr. Limborg, Captain 

 Bmgham, and others, no specimen of so conspicuous a form should 

 have been detected. Had not Peters (P. Z. 8. 1866, p. 429, foot- 

 note) distinctly stated that the types were from Tenasserim, and 

 had not Blyth (Z. c.) confirmed the statement and added that they 

 were collected by Heifer, I should be disposed to regard the locality 

 as very doubtful. I examined the specimens when J was in Berlin 

 two years since, and found them to be labelled "Tenasserim— 

 Prof. Strempel," but I could learn nothing of their history. 



VI. Notes on some of the Varieties of Felis bengalensis, Kerr, 

 and especially on Felis jerdoni, Blyth. 



The wild Spotted Cat of the Indian and Malay forests, appro- 

 priately named the " Leopard-cat " by Jerdon, has been very 

 differently regarded by various naturalists. By some the difiFerences 

 in the size, form, and distribution of the spots, in the tint of the
