Loricella angasi, Ad. and Ang., 1864. I have taken 

 at different times three large specimens alive at Marino in 

 deep holes at lowest tide measuring 67 mm. x 40 mm., and 

 one at Aldinga Bay measuring 67 mm. x 47 mm. 



Onithochiton ashbyi, Bed. and Matt., 1906. Torr 

 (Trans. Roy. Soc. S. Austr., vol. xxxvi., p. 151, 1912) 

 refers to only one specimen having been taken. The type was 

 collected by me at Aldinga Bay prior to 1898 and placed 

 in Mr. Bednall's hands for description. Several years later 

 I took a second specimen from the same spot about a quarter 

 of a mile south of Aldinga jetty in a large sheltered pool. 

 This is the one referred to in Torr's paper, and is still in 

 my possession. "When alive its girdle and valves were 

 brilliant green and pink harmonizing with the calcareous 

 growths on the rock upon which it was found. In January, 

 1918, Dr. Torr was successful in finding a third specimen 

 at Corny Point, Yorke Peninsula. 



Acanthochiton maughani, Torr and Ashby, 1898. In 

 Torr's paper (Trans. Hoy. Soc. S. Austr., vol. xxxvi., p. 162, 

 1912) only one locality is given for South Australia. I 

 collected it at Aldinga Bay in 1897 and at Port Noarlunga 

 and Marino in 1899. It is, as far as my experience goes, 

 always a rare species in this State. 



Acanthochiton cornutus, Torr and Ashby, 1898 (Trans. 

 Roy. Soc. S. Austr., vol. xxii., pt. 2, p. 217, Torr and 

 Ashby). The type locality is given as Marino at low tide. 

 It was taken by me on the reef which at low water is quite 

 shallow, many rocks being exposed. In Torr's paper (Trans. 

 Roy. Soc. S. Austr., vol. xxxvi., p. 161, 1912) he says, 

 "This is evidently a deep-water species." I think it doubtful 

 whether the occurrences he refers to have been correctly 

 identified. I have not myself seen a second specimen. The 

 existence of eyes in the dorsal area, as referred to in the 

 addendum to the original paper by Torr and Ashby, should 

 make it easy of identification. I should be exceedingly 

 grateful to any collector who may meet with this shell if 

 he would kindly place a specimen or specimens at my disposal, 

 in order that the remarkable discovery of eyes in an 

 Acanthochiton may receive further elucidation. 



Anisoradsia mawlei, Iredale and May, 1916 (Proc. Mai. 

 Soc, vol. xii., pts. 2 and 3, p. 108, Nov., 1916). Subspecies 

 saundersi, n. subsp. When at Port Lincoln in January, 1917, 

 with Dr. Torr, I collected several specimens of an Ischnochiton 

 evidently new to this State. On comparing it with 

 Iredale and May's Tasmanian shell mawlei, for which they 

 formed a new subgenus Anisoradsia, a close general 

 resemblance was discernable, but it differs in several respects.
