REPTILES AND AMPHIBIANS. 



595 



The circumference of the body is one twenty-second of the total 

 length. Ventral shields three hundred and twenty ; anal entire, sub- 

 caudals thirteen. Scales in thirteen rows. Uniform black ; on each 

 side of the body a series of round white spots, the first being behind 

 the angle of the mouth, and the last on the very end of the tail. 



This singular Snake differs in so many respects from the typical 

 Calamarice that it may be regarded as the type of a distinct genus, 

 to which the name of Typhlocalamus may be given. Unfortunately 

 the head of the single example has been allowed to dry, and is some- 

 what shrunk ; but it is almost certain that there is no nasal shield. 



The single specimen from Sarawak is 11 inches long, the head 

 being 2£ lines, and the tail 4| lines. 



Simotes subcarinatus. (Plate XXXIX. fig. B.) 



Allied to S. signatus. 



Scales in seventeen rows, minutely striated, and with an obtuse 

 median ridge, like a keel ; these ridges are more apparent on the 

 hinder part of the body than on the anterior. Loreal none, con- 

 fluent with posterior frontal, the lower angle of which is in contact 

 with the second and third labials ; one prae-, one postocular ; seven 

 upper labials, the third and fourth entering the orbit ; temporals 

 1 + 1-1-2. Anterior chin-shields twice as long as broad, and twice 

 as large as posterior, in contact with tour labials. Ventral shields 

 1 58 ; anal entire ; subcaudals 54. Ventrals without keels. Greyish 

 olive, with numerous narrow, straight, white, dark-edged cross 

 bars ; they are placed at rather irregular intervals, some reaching 

 right across the back and sides, others being much shorter. Head 

 with the markings usual in this genus. Abdomen white, with some 

 darker spots along each side. 



One specimen from Sarawak is 15 inches long, tail 3| inches. 



Ablabes periops. (Fig. 3.) 



Eye surrounded by a ring of small scales. 



Scales in seventeen rows, short, rounded, without apical groove. 

 Rostral shield broader than high, just reaching the upper surface
