 bv Mr. Atkinson, on the N. W. Coast, and several specimens 

 have been dredged by Dr. Verco in South Australian waters.)

Tenison-Woods" description is exceedingly good for pur- 

 poses of distinguishing this species. It is dotted all 

 over with minute depressions, the lateral areas are only 

 slightly elevHted, the girdle is membranaceous, and is much 

 broader than that of C. platessa. The colour when alive 

 is a rich red all over, and the colour is uniform on valves 

 and girdle. Several specimens! were taken by W. G. Torr 

 from Burnic, Devonport, Ulverstone and Stanley. The 

 largest dried specimen measures 60 m.m. by 30 m.m.

We confess to some difficulty in separating /. longy- 

 cimha (Reeve), /. haddoni (Pilsbry), and /. crispus (Reeve), 

 but the Tasmanian specimens are so much like those on 

 the Australian continent, known as /. crispus, that we 

 have placed them as one species. 



/. crispus is the commonest ischnochiton in Tasmanian 

 waters, and is found all round the coast. It has been 

 found by W. L. May along the East Coast. It is 

 some hat less plentiful in the Southern Bays, but W. Gr. 

 Torr found large numbers along the Nortn Coast. It 

 is a shell of many colours, and endless variety of mark- 

 ing?. Brown, gi'een, olive, black, with white stripes, 

 and white with black stripes. A very unusual five- 

 valved specimen was found by W. G. Torr, at Ulverstone, 

 in July, 1908. Several specimens of the colour variety 

 known as /. crispus, var. decoratus. were founrl along the 

 North Coast, and also in Frederick Henry Bay.
