lacowie and a valve at Corney Point. It has been dredged 
by Dr. Verco, and seems to confine itself to Spencer and St. 
Vincent gulfs. My specimens are not the largest found, 
although I have them 45 x 25 mm.

This, the most beautiful of all South Australian 
Chitonide, may be only a colour variety of exoptandus, but 
the uniformity of its green colouring differs so much from 
the pinkish tinges of exoptandus that it may well be classified 
and named after the doyen of Polyplacophora writers in South 
Australia. I have a specimen from Sultana Bay, a valve 
from St. Francis Island, a valve dredged from 25 fathoms in 
Thorny Passage, and several specimens dredged by Dr. Verco 
in Gulf St. Vincent. Size, 40x20 mm. One specimen was 
found by Mr. Kimber at Aldinga (South Australia), and 
Mr. Sykes reports it from Port Philip.

This chiton strongly resembles the drawings of Chiton 
huttoni, Suter, Trans. N.Z. Inst., vol. xxxviii., 1905, p. 321, 
pl. xviii., figs. 1-6; but the slope of the tail valve is much 
steeper in CU. verconis, and the pointed girdle scales are 
decidedly different. These scales are very similar to C. 
limans, but in the latter there are no striations. CU. verconis 
has been dredged by Dr. Verco in Yankalilla Bay, 9 fathoms; 
Rapid Head, 9 to 11 fathoms; and in Spencer Gulf. All my 
specimens have been dredged. Mr. W. D. Reed has dredged 
it in Spencer Gulf, and it has been taken at Aldinga by Mr. 
Kimber. I have a very fine specimen labelled Port Fairy 
(Victoria), from the late Mr. Adcock’s collection.

This shell has been found only on the south-east coast 
of South Australia. One specimen comes from Cape Jaffa 
and several have been taken at Port MacDonnell. It ought 
to be in Victorian waters. Mr. Maughan’s description is very 
helpful, but the plates are very indistinct.
