OF NEW SOUTH WALES. 41 



posterior ocular; scales in 21 rows; abdominal shields 113, subcau- 

 dals 24 undivided, the others not complete; total length, 17 

 inches ; tail, 2| inches ; colour, uniform very pale brown above, 

 beneath yellow ; the lower labials have each a large black spot, 

 the last upper labial and the temporal shield abutting on it are 

 similarly marked, there is also a black semicircular groove in 

 front of tlxe rostral shield ; the abdominal and subcaudal shields 

 are broadly barred with black, interrupted in the middle on the 

 body, but continuous on the tail ; there are also spots on the outer 

 body scale on each side. 



Most unfortunately the tail in my only specimen is imperfect, 

 but I am satisfied that it is really an Acanthophis, notwithstand- 

 ing the smooth scales ; in almost every other respect it agrees 

 with the generic characters of Acantlwpliis. 



It was procured at Katow.

One young specimen was taken in Hall Sound, and it was the 

 only sea snake captured during the Expedition. A species was 

 frequently seen, however, lying on the surface of the water, but 

 it invariably went down as the ship approached. I made an effort 

 at Darnley Island to get the natives to procure me a specimen of 

 it, but they assured me that the snake never left the water, and 

 that it was impossible to get it. The colour seemed to be uniform 

 yellow, the length from 3 to 4 feet, and the thickness quite 2 

 inches.
