brown, with obsolete black imiigins. They are included between the 

 sixth and seventh rows on each side, and about six scales long. They 

 are very regular in shape, longitudinally (juadrate, rather wider trans- 

 versely in the middle, and with the corners slightly produced longitu- 

 dinally. The gray intervals are thus not quite rectilinear, rather 

 elliptical, but of the same width throughout. On the second, third, 

 fourth, and lifth lateral row is a second series of similar blotches, more 

 or less elongated, especially anteriorly. On the side of the neck, indeed, 

 the blotches are confluent into very narrow distinct strijies. A third 

 series of square blotches on the side of the abdomen, involving the first 

 and second lateral rows. Rest of belly yellowish white, with black 

 blotches; anterior eighth immaculate. A black stripe from the pos 

 terior part of the orbit to the angle of the mouth, which it reaches on 

 the anterior extremity of the last labial. A vertical line beneath the

eye, and the edges of the labials in front also black. Some blotching 

 on the top of the head, which is too indistinct to define and is sometimes 

 entirely wanting. 



Compared with 8. vulpinus the eyes are larger, the parietal plates 

 longer, the nostrils more anterior, the carination more obsolete. Body 

 more elongated. Abdominal scutell;« more numerous. Spots longitu- 

 dinal, not transverse. Scales shorter, broader, more obtusely angular. 



This species is closely allied to ^S*. ffuttatus, but is quite distinct. Its 

 full characters can best be seen in larger specimens ; the young are more 

 easily confounded with those of *S'. guttatus.
