560 MU. E. A. SMITH ON MARINE SHELLS 



89. Stomatella haliotoidea, Sowerhy, A. Adams in Sowerby's 

 Thesaurus Conchyl. ii. p. 837, pi. 164. f. 10, 11. 



Hab. San Christoval, Solomon Islands (Brazier) ; Philippine Islands 

 {Cuming). 



The shell sent by Mr. Brazier is of a uniform olive-green, and 

 dirty white in the umbilical region, and dotted with white upon 

 the spiral lirse. These are subequidistant and very fine ; and be- 

 tween them tbe shell is very finely spirally striated. 



90. Emarginula variegata, A. Adams, Proc. Zool. Soc. 1851, 

 p. 84; Sowerby, Thesaurus Conchyliorum, iii. pi. 245. f. 9, 10; 

 Reeve, Conchol. Icon. vol. xix. 



Hab. San Christoval, Solomon Islands (Brazier) ; Philippine Islands 

 (Cuming) ; Australia (Sowerby). 



The species is described by Adams as " albida, rufo-fusco varie- 

 gata," and by Sowerby as " alba griseo variegata ;" and the figure 

 in the ' Thesaurus ' represents it as white, variegated with pinkish 

 purple, with darker spots on the ribs. The latter coloration 

 agrees best with certain specimens in the Museum ; and others 

 are almost entirely of an obscure purplish tint, with scarcely an}'- 

 white markings. The specimens from the Solomon Islands are 

 dirty white, with most of the radiating ridges of a blackish 

 colour, and very finely granose. 



91. Tellina christovalis, sp. nov. PI. XXX. fig. 22. 



Testa seqnilateralis, sequivalvis, rotunda subtriangularis, aliquanto tumida, 

 alba, macula rufescente magna subtriangulari versus umbones picta, 

 polita, concentrice tenuiter striata ; margo dorsalis utrinque valde 

 declivis, et paululum arcuatus, ventralis arcuatissimus, postice levis- 

 sime sinuatus. Long. 7^ mill., lat. 9, crass. 4|. 



Hab. San Christoval, Solomon Islands. 



There is a single specimen of this little species in the Cumin- 

 gian collection from Upolu, which is a trifle larger than the 

 above dimensions, but agreeing in all other respects with that 

 from San Christoval. The reddish spot, which is somewhat 

 triangular in form, and stains the valves towards the umbones, is 

 also seen within them. The shining surface is slightly prismatic 

 in certain lights. 



92. Thracia Angasiana, sp. nov. PI. XXX. fig. 23. 



Testa alba, tenuis, insequivalvis, ovato-oblonga, postice angustata et 

 rotunde truncata, mediocriter insequilateralis, concentrice tenuiter 

 striata, obscure et minutissime granosa ; margo dorsalis antice 

 arcuatus, postice decliviter rectiusculus, ventralis antice arcuatus.
