334 STUDIES ON AUSTRALIAN MOLLUSCA, xi., 



Ophicardelus stutchburyi Pfeiffer. 



(Plate xix., fig. 88.) 



Melampus stutchburyi Pfeiffer, Proc. Zool. Soc, 1856 (1857), p. 

 393; Id., Gassies, Faun. Conchyl. Nouv. Caled., 1871, p. 105; Id., 

 Brazier, These Proceedings, ii., 1878, p. 134. 



This species is represented in the British Museum by a set of 

 six, marked types, and labelled "Melampus stutchburyi Pfr., P.Z.S., 

 1856, p. 393. Mr. Stutchbury, M.C." 



Gassies erroneously united this with the Tasmanian 0. omatus, 

 but it is far closer to 0. sulcatus. 



These type-shells are 17 mm. long, and 9 mm. broad. In colour, 

 they vary from brown with a narrow white line on the shoulder, to 

 white with three revolving brown lines.

Melampus tetricus Morelet, Journ. de Conch., xii.,1864, p. 290. 



Ophicardelus irregularis Mousson, and 0. minor Mousson, 

 Journ. de Conch., xvii., 1869, pp.64, 65, PI. v., figs.2, 3. 



In the British Museum are three, marked type, labelled "Mel. 

 tetricus, Morelet, Nile. Galles du Sud. J.d.C, 1864, p.290." This 

 unfigured species proves to be a squat variety of 0. ornatus. 



Judging from specimens from the type-locality, and from the 

 figures and descriptions, I consider that 0. irregularis and 0. 

 minor are abnormal or deformed specimens of 0. ornatus. 



Seeing that Quoy & Gaimard obtained their types of 0. aus- 

 tralis near Hobart and in Western Port, it is improbable that 

 Crosse was correct in recording that from New Caledonia.
