where. It is, perhaps, worthy of notice that none of the poisonous 

 Snakes are peculiar to the island ; and, on the whole, we may say 

 that this part of its fauna, so far as it is known at present, does not 

 , essentially differ from that of the other large Malasian islands. 



I proceed now to the description of some species which appear to 

 be new ; and I take this opportunity of noticing a few additional 

 species from other parts of the East-Indian archipelago. 



Draco cristatellus. (Plate XXXV. fig. A.) 



The length of the hind limb equals the distance between the axils 

 of the limbs. Nostrils lateral, obliquely directed upwards and out- 

 wards. Male with a slight nuchal crest in the form of a low fold. Tail 

 crested, the crest being formed by rather distant, triangular, pointed 

 scales. Scales small, those on the back smooth, without scattered larger 

 ones ; abdominal scales keeled. Orbit without prominence above. 

 Tympanum nearly entirely scaly. Upper parts light chestnut-brown, 

 with irregular transverse black markings. Gular sac golde°n-yellow, 

 with a brown anterior edge. Lower side of the wings nearly uniform 

 whitish, with only a few blackish spots along its anterior margin. 



One adult male from Sarawak. 



Ift'&i ^ RACO spiLofofjtitajs. (Plate XXXV. fig. B.) 



The length or the hind limb equals the distance between the axils 

 of the limbs. Nostrils lateral, directed outwards. No crest. Scales 

 small, those on the back smooth, without scattered larger ones, all 

 much smaller than the upper labial shields ; abdominal scales keeled. 

 Orbit without prominence. Tympanum distinct. Upper parts mar- 

 bled with brown ; sides of the neck reticulated ; wings yellowish 

 white, with small black spots on their basal half, which are visible 

 on the upperside of the wings as well as on the lower. 

 Two specimens from Manado. 



Tiaris liogaster. (Plate XXXVI.) 



Dorsal crest continuous, very high in the adult, disappearing on 

 the front part of the tail. Sides with irregularly scattered larger 

 scales. Scales of the median line of the gular pouch not conspicu- 

 ously different from those on the side of the pouch. Abdominal 

 scales of moderate size, smooth, or with a very faint keel. The 

 middle of the upper arm surrounded by about seventeen or eighteen 

 longitudinal series of scales. Tympanum as large as the eye. Throat 

 with black spots, more or less distinctly arranged in oblique series 

 converging towards the median line of the pouch. 



Three adult, one half-grown, and one young specimen from Sa- 

 rawak. 



Tiaris miotympantjm. (Plate XXXVII. fig. B.) 



Dorsal crest continuous, high in the adult, rather abruptly termi- 

 nating on the root of the tail. Sides with a series of larger scales 

 along each side of the back ; no other scattered large scales on the 

 side. Scales of the median line of the gular pouch not conspicuously
