characteristic, but the body scales are arranged in 15 instead of 17 series. In 
other respects the lepidosis is as described. 
PSEUDECHIS WILESMITHII, Be Vis.* 
Amended description and note on affinity with P. scutellatus, Peters. — 
The type specimen named as above is one of the longest Australian venomous, 
snakes yet received by the Queensland Museum. Its length (body removed from 
skin) is no less than 2,215 mm., of which the tail is 340 mm. Owing to extraction 
of the venom glands, the head is in a somewhat damaged condition. The rostral 
was originally described as being one-fourth longer than broad, whereas the 
breadth is slightly in excess of the length. On one side only are there two 
pneoculars, and there are but six upper labials. On the left side the lower 
anterior temporal is wedged in between the fifth and sixth labials forming the 
seventh shield noted by De Vis. The lower angle of this shield fails to reach 
the gape on the right-hand side. There are three lower labials in contact with 
the anterior chin-shields. The diameter of the eye slightly exceeds the distance 
from the mouth, but owing to the state of the head the proportion cannot be 
obtained with accuracy. With these necessary emendations, the specimen 
demonstrates so close an alliance with P. scutellatus, Peters, that the writer 
doubts the wisdom of separating them. It may be noted, however, that the 
frontal is slightly wider than either of the supraoculars, and is but one and 
a-half times as long as broad. On each side the posterior nasal is separated from 
the pneocular by a space of 2 mm. In a specimen of P. scutellatus, received 
from Mr. W. H. Edwards, Colosseum, North Coast line. Queensland, the frontal 
is also slightly wider than either of the supraoculars, but its length is almost 
twice the breadth. In colouration both examples are brown, one being darker 
than the other. The lighter colour on the snout and sides of the head is 
noticeable in each.
