SOMK NEW OK NOTEWORTHY SHELLS — HKDLEY. 133 



iunow, in the deep valve by a ridge. Continuous over all is a 

 n)iciosco[)ically grained surface. Length, 36 ; height, 29 ; depth 

 of single valve, 5 miu. 



This fine species has some resemblance to M. striata, Quoy 

 and Gaimard, from New Zealand. But that is more strongly 

 scul|)t,ured, more solid, more inflated, and shorter in proportion 

 to height. 



Hah. — I collected several specinienH of this on the beach at 

 Mapoi)n and Karumba. At Mapoon I found also another 

 apparently new species more compressed, more delicately sculp- 

 tured, and with the posterior area less diflferentiated. 



LOKIPES ASSIMILIS, AuyaS. 



Loripes nssimilis, Angas, Proc. Zool. Soc, 1867, pp. 910, 926, 

 pi. xliv., fig. 8. 



Lucina (^Loripes) jacksoniensis. Smith, Chall. Rep., Zool., xiii., 

 1885, p. 185, pi. xiii., fig. 11. 



Both of these were described from Sydney Harbour ; the 

 •discrepancy between the accounts may be reconciled if we 

 considered that the single specimen used by Smith was worn but 

 that Angas had fresh material. For good specimens show fine 

 close concentric laminae but no trace, or hardly any, of radial 

 lines. As wear of the shell proceeds, the lamellae go, and over 

 the whole shell appear fine close radial Hues, which are not 

 surface sculpture, but opaque substance within the shell, 



Mr. C. J. Gabriel with whom I have discussed the subject and 

 who examined the types of each in the British Museum agrees 

 with me that these names should be united. 



Angas contrasted his L. assimilis with L. icterica, Reeve. No 

 locality for that species was given by Reeve, and Mr. Gabriel 

 was unable to find Reeve's type in the British Museum. I 

 suggest that the Sydney shell which Angas rightly or wrongly 

 took for L. icterica was that afterwards called Lucina ramsayi 

 by Smith. In that case Angas used small examples, for in my 

 experience L. ramsayi exceeds L. assimilis in size. It is also 

 likely that the L. icterica, Reeve, which Melvill and Standen* 

 reported fiom Warrior Island was also L. ramsayi, as I found 

 that species on Murray Lsland.
