of a red crispus in South Australia similar to what Suter 

 called /. fulvus. On his return to South Australia some 

 specimens were sent to Mr. Suter, some of which were identi- 

 fied with I. fulvus, others with I. crispus. Some very beau- 

 tiful specimens of I. gryei were taken off Port MacDonnell 

 jetty and Cape Jaffa. The identification will require future 

 consideration. Mr. Sanders found several diminutive speci- 

 mens at Second Valley, which I take to be gryei.

Strongly resembles I. australis, Sowerby, but the lateral 

 areas of australis are much more deeply sulcated than those 

 of novce-hollandice, and the pleural areas of the former are 

 longitudinally ribbed, although I have found some novce- 

 hollandice slightly ribbed in the pleural areas. 



Some specimens in my collection labelled Marino, South 

 Australia, are certainly /. australis, but further investigation 

 must be made before placing it on the list of South Aus- 

 tralian chitons. 



/. novce-hollandice favours the open ocean beaches. I 

 have specimens from Encounter Bay, Tungkalilla (large num- 

 bers), Kangaroo Island, and Second Valley; also from 

 Penguin, Stanley, Wynyside, and Devonport in Tasmania, 

 and Beaumaris, New South Wales. One dried specimen is 

 65 mm. long and 35 mm. broad. /. australis is common in New 

 South Wales. The Tasmanian species show longitudinal 

 riblets in the pleural areas.
