d. A stuffed adult, No. SOD of Blyth^s Catalogue : hands 

 paler than No. 125, and feet yellowish. Ceylon. Presented

Blyth described S. priamus as having a compressed, high, 

 vertical crest, but one of the foregoing specimens (c) shows 

 no sign of a true crest, and, as Blyth stated that the specimen 

 which was under his observation when alive had no crest, I 

 examined the types of the species a and h, and found that in 

 a the skin of the vertex had been cut open and cotton wool 

 introduced between the skull and the skin, and that where 

 the cotton wool was there the crest existed. In h the short 

 compressed crest occurred exactly over the point of a wire 

 that perforated the skull and pressed against the skin.

The skull of S. priamtis, in its adult condition, is consider- 

 ably smaller than that of S. enlellus ; the vertical depth of its 

 face is relatively less than in that species, while, on the other 

 hand, it is proportionally broader across the orbits. Its fronto- 

 nasal depth also is less than in S. entellus, the nasals being 

 short and broad, and the nasal opening considerably shorter 

 than in that species ; a line drawn through the centre of the 

 face, from the alveolar border of the premaxillaries to the 

 supraorbital ridge, does not touch the distal end of the nasals, 

 these bones being rather flattened and broad, and slightly
