suture of the postfrontals, and is continued beneath the eye on the suture of 

 the fourth and fifth labials. A longitudinal black band proceeds from the 

 transverse, passes through the middle of the vertical and along the suture of 

 the occipitals, then widens and bifurcates on the neck. A crescentic black 

 mark begins near the exterior border of the occipital plate, and extends a 

 little beyond the commissure of the mouth, crossing the seventh upper labial.

The second of these specimens has, alternating with the cros3 bands, a 

 transverse series of four separate spots; two dorsal, rounded, and one on each 

 side, narrow. 



93. S. aphanospilus nobis. In this species the head and investing plates 

 are shorter and broader than those of the last species ; the sides of the vertical 

 shields are more convergent posteriorly. As in other Simotes there are one 

 pre- and two postoculars. Loreal a little longer than high ; upper labials seven, 

 third and fourth entering the orbit ; inferior labials eight, the posterior one 

 very small. Scales large, obtuse, imbricate, in seventeen rows. Geneials two 

 pair, the posterior half the length of the anterior. Gastrosteges 173, anal one, 

 urosteges 37 pairs. Length of body and tail 23 in. 5 1. ; tail alone 3 in. 4 1. 



The color of the upper surface of this serpent is a dull olive brown. From 

 the neck to the base of the tail we count thirteen nearly equidistant scutcheon- 

 shaped figures, brown bordered with black. These extend a short distance on 

 the flanks, and are sometimes confluent with another series of smaller, similar 

 figures on each side. In the middle of the interval between each dorsal figure 

 is a small black spot. On the head the arrangement of markings is similar to 

 that of the last species. They are, however, only indicated by narrow black 

 borders enclosing the ground color. Lips and beneath dirty yellowish. 

 One specimen. Philippines. Mr. Cuming, in ex. 



The two species preceding are nearly allied to the S. purpurascens 

 Gthr., but comparison with the figures of Schlegel and Dum. et Bibr. at once 

 reveals the differences in the markings of the head. The number of labials is 

 also different.
