One specimen, 10 inches long, was obtained by Mr. Theobald 
on the Arrakan Hills. — 
Simotes cruentatus. 
Scales in seventeen rows. One pre- and two postoculars ; 
loreal rather longer than deep; eight upper labials, the fourth 
and fifth entering the orbit; temporals 1+2; ventrals 165- 
167; anal bifid; subcaudals 33-37. | 
Head and neck with the markings usual in the species of 
_ this genus rather indistinct. Body brownish olive, with four 
very indistinct darker lines ; abdomen white, with square black 
spots; anal shield white; the three or four first subcaudal 
shields black, the others red; generally another black spot at 
some distance from the end of the tail. 
- We have received several examples, under the name given 
above, from Mr. Theobald, who discovered this snake in Pegu. 
The largest of the specimens is 15 inches long; one female 
example, 13 inches long, has five ova in the oviduct, each 
ovum being 9 lines long. 
Simotes Theobaldi. 
- Scales in seventeen rows. One pre- and two postoculars ; 
loreal much longer than high ; eight upper labials, the fourth 
and fifth entering the orbit; temporals 1+2+43,; ventrals 
177; anal bifid; subcaudals 34. 
Head and neck with the markings usual in the species of 
this genus; upper parts of the body brown, with a light ver- 
tical line commencing from the occiput and longitudinally
