Mitra cookii Sowerby. 



Mitra cookii (Hanley, MS.) Sowerby, Thes. Conch., iv., 1874, p. 

 7, PL 354, fig. 228. 



This shell has not been localised hitherto more exactly than 

 "Australia," and the name has escaped the attention of local 

 collectors. It is, however, common about Sydney, and is evidently 

 the species erroneously recorded by Angas* as Mitra variabilis 

 Reeve. It also occurs at Caloundra, Queensland. In the British 

 Museum are two, marked "type, cookei, Sowerby, Australia." These 

 are slender, 35 mm. long, encircled with fine punctate striae, colour 

 chocolate-ochraceous with a pale median zone. 



Mitra legrandi Tenison- Woods.

It has been considered by Tate, May, Pritchard, and GatlifT,f 

 that M. legrandi Ten. -Woods is identical with M. schomburgki 

 Angas. As M. legrandi dates from 21st March 1876, and M. schom- 

 burgki from 1st August, 1878, the name of Tenison-Woods should 

 take precedence were they united. But, for the following reasons, 

 I consider them distinct. 



In the British Museum are two, marked "Types, Mitra schom- 

 burgki, Angas, South Australia and Port Phillip. Pres. G. F. 

 Angas, 78/4/10." Again, in the same collection, is one marked 

 "Type Mitra legrandi T. Woods, Tasmania." The latter agrees 

 exactly with my figure, and differs from M. schomburgki in form, 

 colour, and sculpture. M. schomburgki is more contracted at the 

 base, has more ribs, and wants the peripheral colour-line of M. 

 legrandi. 



Three specimens from South Australia, presented to the British 

 Museum by G. F. Angas, are determined as M. analog ica Reeve, j
