Some Additions to the List of the Marine 

 Gastropoda of South Australia. 



By Professor Ralph Tate. 

 [Read June 6, 1893.] 



In the recently published " Hand List of the Aquatic 

 Mollusca inhabiting South Australia," Mr, Adcock, the compiler, 

 has made me responsible for some specific names which are in 

 reality only manuscript ones. In the foregoini>- paper I have 

 established the major part of those names by appropriate 

 diagnoses and figures. 



Whilst the " Hand List " was passing through the press I had 

 not the opportunity of consulting my cabinet, and as a conse- 

 quence some species escaped notice ; and, moreover, in the mean- 

 while some species have been added to the fauna through the 

 dredging operations conducted by Dr. Yerco during January of 

 this year. 



Briefly, then, this communication consists of addenda and 

 corrigenda to the " Hand List," and the numerals in brackets 

 prefixed to the species-names arc in correspondence with those in 

 that publication.

Tro2)hon U7nbilicatus, T.AVds., Proc. Roy. Soc. Tasmania, for 

 1875, p. 135 (1870). 



This species is distinct from J/, octoyonus, Q. tfe G., as pointed 

 out by Mr. Brazier, an opinion with which we concur. M. scalaris, 

 Adams, is an older name, but as it is preoccupied for a well-known 

 fossil of the Piedmontese Pliocene, Tenison-Woods' name appears 

 in substitution. 



SiphO (?) mimetieus, Tafe (ante p. 189). 



(39). Latirofusus nigrofuseus, Tate. 

 Since the publication of my diagnosis and figure of the above- 

 named species, I have examined several private collections of 

 Tasmanian shells in Hobart and Launceston and the local collec- 

 tion in the Hobart Museum. In these I And the names of Fusils 

 Sjnceri and F. Legrandi indiscriminately applied ; and I am not 

 sure that I have seen the type of either. But from Woods' 

 description, I do not hesitate to select F. Spice7'i as the one 

 which is synonymous with my Latirofusus nigrofuseus., the other 

 shell I consider to be a young state of Siphonalia sulcata. The 

 specimens received from Mr. Legrand, which were said to have
