SITTER : ON NEW ZEALAND PATELLID^. 355 



I am confident that mj- collection now contains all the species of 

 Patellidse to be found in New Zealand waters, and I am unable to find 

 anything amongst them corresponding with Reeve's species. Without 

 seeing the type-specimen, it is not easy to locate this form, but I fully 

 agree with Mr. E. A. Smith that it is an Acnuea, and there is no other 

 New Zealand species attaining that size but Acmtea pileopsis, Q. & G. 

 This also is a veiy variable species, but I have examples which are 

 decidedly convexly depressed, have the apex situated as the figure 

 of floccata indicates, and several specimens are profusely and radiately 

 dashed with white flakes. 



Patella Magellanica, Gmel. 



Filhol records this species in the Miss, de File Campbell, p. 528. 

 I have seen specimens from South America, but never anything like it 

 from the Southern Islands of New Zealand. It seems that Filhol was 

 partly misled by Hutton's enumeration of P. Magellanica in his Man. 

 N. Zeal. Moll., and it is most likely that he also took H. strigilis for 

 Magellanica. Without having seen the specimens collected by the late 

 Dr. Filliol, it is of course impossible to be quite positive on this point. 



In Capt. Hutton's revision of 1884 the following species were 

 omitted as not really inhabiting New Zealand : — Patella granularis^ L., 

 and cochlear, Born, fi'om South Africa, and stella, Lesson. Habitat 

 unknown. 



The last mentioned is no doubt an Acmcsa, and I have examples 

 from New Zealand corresponding with Lesson's diagnosis ; they are 

 very near A. corticata, Hutt. I shall deal with this form in my 

 revision of the Acmseidse of New Zealand, which I hope to work out 

 some day.
