SMITH : NEW SHELLS FROM ATJSTRAXASIA. 59 



ginem hand crenulata, limbo angusto, flavo, radiis rufo-nigris notato, 

 circumdata. Long. 11-5, diam. 9 mm; alt. 4mm. ^«5.— Greymouth, 

 Westcoast of South Island, I^ew Zealand (collected by R. Helms). 



This species appears quite distinct from the other forms recorded 

 from New Zealand. The interior in coloration somewhat resembles 

 that of Patella floccata, Eve., but in other respects this species is very 

 different. It is smaller, the form is more cap-shaped, the apex is 

 more terminal, and_ the radiating lines are regular and not broken 

 up as in that species, which, as seen from above, has a tesselated 

 aspect. ^ The number of radiating lines appears to vary from forty 

 to fifty judging from the examples at hand. 



P. floccata is retained in the genus Patella by Pilsbry, but, 

 from the appearance of the shell, I should be inclined to locate 

 it in Acmcea. Hutton also has placed it in Patella, It is con- 

 sidered by both of these authors synonymous with P. pholidota 

 of Lesson, and the latter is held by Pilsbry to be a variety 

 of the well-known P. radians of Gmelin. This appears to me an 

 erroneous conclusion, for several of the characters described by Lesson 

 are not applicable to P. radians. Neither do I believe that Reeve's 

 P. floccata is synonymous with P. pliolidota or radiayis. 



I would here also call attention to another ' lumping ' of species 

 from New Zealand. Pilsbry states that " P. affinis of Reeve scarcely 

 differs from the typical radians^ He certainly has never seen 

 P. affinis, or he would not have made such a statement. It is quite 

 distinguishable by its peculiarly elongate form. The locality, 

 "New Zealand," is only on the authority of Mr. Cuming. 



Lepeta (?) ALTA, n.sp. PI. Vlt. Figs. 6, 7. 



Testa parva, alta, capuliformis, convexa, flavo-alba, concentrice et 

 radiatim tenuissime striata; apex subcentralis, acutus, recurvus ; 

 apertura rotunde ovata ; peristoma simplex, acutum ; cicatrix interna 

 antice peculiariter incurvata et reflexa. Longit. 7, diam. 6 mm ; alt. 

 5-5 mm. Eab. — Off Sydney, in 410 fathoms, station 164. 



This curious little species was obtained by the '• Challenger " 

 Expedition at the above station, and has been kindly placed in my 

 hands for description by Mr. J. C. Melvill. It is provisionally placed 

 in Lepeta, as conchologically it appears to agree with the typical 

 forms of that genus. It is whitish and invested with a thin epidennis 

 like L. coeca, and is radiately and concentrically sculptured. 



I would take this opportunity of recording the occurrence of certain 

 species at this same locality, Station 164, which hitherto have been 

 regarded as peculiar to the Atlantic. The specimens in question were 

 picked out of samples of sea-bottom, which have been examined since 

 the reports on the Gastropoda and Lamellihranchiata by the Rev. R. 

 Boog Watspn and myself respectively were published. Mr. Watson," 

 who examined the Gastropods, questioned the correctness of the 

 locality from the presence of these Atlantic forms, and was inclined to 

 believe that some mistake must have occurred. I also at first held
