Notes on South African Mollusca. 103 



to Marinula at all ; but it was on two of these sets that writers of 

 the mid- Victorian period based their idea of King's genus. In the 

 Cuining collection also are two sets of the true pepita, labelled re- 

 spectively, " M. marinella, King, Chili " (an apparent misspelling 

 of the Generic name), and "Marinula nigra, Phil, var., Chiloe." 

 Now, in 1844, Kiister described and figured as Auricula pepita a 

 shell from Chili, similar to those wrongly labelled pepita in the 

 Cuming collection ; and also described Auricula nigra, Philippi 

 from Chiloe, afterwards substituting the name A. marinella, King, 

 which he thought had priority. 



The figure is very bad, but the description is that of the true 

 pepita, which came from the same locality as the M. nigra and 

 marinella published by Kiister; and the substitution of the latter 

 name is obviously due to the above-mentioned misspelt label. 



Although Gray more than once" mentioned Marinula, the first 

 authors to make prominent use of it were H. & A. Adams, who, 

 in 1854 f included in the genus; pepita, King ( = triplicatus, 

 Anton) ; patula, Lowe ; marinella ( = nitjra] ; callaoensis, Petit 

 (nomen nudum) ; recluziana, Petit ; cymbaeformis , Eecluz (also 

 nomen nudum); punctata, Bivona ( = villosa, F6r. and firminii, 

 Payr.); aequalis, Lowe (cum var. gracilis, Lowe), and a new 

 species, xantliostoma, from Moreton Bay. 



In 1855 | they practically repeated the foregoing list, but 

 founded a new subgenus Monica, to contain aequalis, Lowe (Type), 

 firminii and gracilis. 



These three species appear to have no connection with typical 

 Marinula, but I hardly see how they can be considered even 

 subgenerically distinct from Phytia, Gray ( = Alexia, Leach, 1847, 

 nee Stephens, 1835). If they are, Monica stands ready to receive 

 them. 



In 1855 Swainson created a genus Gremnobates for three 

 Tasmanian shells, which he described under the names of C. cornea, 

 parva and solida. Hedley & Suter || have shown that cornea and 

 solida are respectively synonyms of Ophicardelus australis, Q. & G., 

 and the M. patula, Lowe, of Pfeiffer, and therefore propose parva as 

 Type of Swainson's genus ; but parva appears to be a true Marinula, 

 in which case Cremnobates can only be relegated to synonymy.
