longer than high ; one narrow but high pre-ocular, reaching to the 

 top of the head, and in contact with the posterior frontals ; two 

 post-oculars, the lower one forming the edge of the orbit and joining 

 the pre-ocular ; temporal 1 -|- -j, there being one conspicuously- 

 large, second temporal behind the first in contact with the occipitals. 

 Eight lower labials, the two first form a short suture and are 

 followed by two pairs of subequal chin-shields. 



Colour above dull yellow with numerous broad bluish black 

 bands, separated on the back by narrower interspaces, becoming 

 rapidly wider at the sides, and the black bands are obsolete before 

 they reach the ventrals ; on the posterior part of the body some of 

 the bands are confluent, and on the tail they even partially form 

 rings ; head with a yellow band across the posterior frontals, dark 

 on the top (including the eyes), with a few yellow spots on the 

 occipitals and vertical ; below uniform pale yellow with a dusky 

 greenish tinge along the middle of the ventrals. 



There are four teeth in each maxillary, the last is the largest and 

 indistinctly grooved ; on one side one small additional tooth is be- 

 tween the first and second, and another one between this and the 

 third. 



A single specimen was obtained by me near Amherst at the 

 mouth of the Moulmein river in brackish water ; it measures 30^ 

 inches of which the tail is 3£. In coloration and general habit it 

 strongly resembles Sipistes hydrinus, in company of which it was 

 procured, but it appears to be very rare. Captain Gr. E. Fryer 

 sent about ten fishermen for me to work ; they brought in one morning 

 at least 60 specimens of Hipistes hydrinus and a great many Cerberus, 

 but only a single specimen of this new species. I have great plea- 

 sure in naming it after my friend, Surgeon F.Day, whose pleasant 

 company made my short stay in the neighbourhood of Moulmein 

 quite as instructive, as it was a source of recreation and of pleasure.
