' Thiss^ecliis[Nijmpkonhr,i-icaHi!atmn] is alliinl to the boreal N. hrevitum:, Kvoycv ; but it is distingui.-ibeil I'y 

 its more robust form, its long :iiitl slender oeuligevous tubercle, its longer tarsal joints, &c.— (E. J. Miers, Phil. Trana., 

 vol. 168, \). 213.) 



" Cardita aslwtoiiks, as pointed out by Martens, bears a great resemblance to the North American Cimlitu iHtrealit!, 

 and may be regarded as the southern representative of that form. It certainly is more like that species than Carthtii 

 velitlinii from South Patagonia, whiih we should not expect, considering how similar the fauna of that region and of 

 Ivergueleu Island appear to be.— (.^mith, j^uuI. Chall. Kxp., part 35, pp. 212, 213.) 



'•' Cniptoihm iiianoiunsis is the southern form of Cnjptochm goiddii, Philippi, and Crijjitodon flfxiiosii.t, Montagu, 

 both of which species it closely resembles.— (Smith, Zoot. Cliall. Exp., part 35, p. 194.) 



■* Two specimens from Kergueleu 1 cannot distinguish from this well-known European species [Kdlia sidiorbiculurin], 

 which has not, I believe, ))oen i)reviously met with fai-ther south than the Canaries. — (Smith, Zool. Cliall. E.vp., pirt 

 35, p. 201.) 



'' This polymorphous species [Saxicava arcfo'ca], judging from the shells alone, is apparently distributed all ove 

 the globe. Of the animals inhabiting them \vi^ know nothing except those of northern varieties. The sliells vary 

 immensely in form, thii'kuess, and ornamentation. Tliose found olT the South African coast are especially remarkable 

 for the great development of the spines on the posterior side, and have been raised to specilic rank by Mr Sowkriu 

 uuilcr the name of Saxicara spinifi^ni. Many localities have already been cited for this species, and among them may
