150 SOWERBY : MARINE SHELLS OF SOUTH AFRICA. 



Oliva caerulea Bolten. Yery common in the Indian Ocean, 

 but rarely found on the South African Coast. 



O. bulbosa Bolten. Several varieties of this common well- 

 known Indian species have been collected at Port Elizabeth 

 by Mr. Bairstow. 



Ancillaria australis Sow. This common New Zealand 

 species has been found for the first time at South Africa by 

 Mr. Bairstow. The specimens are dead and somewhat dis- 

 coloured. The species resembles A. obtusa, but the spire 

 is much more acute. As far as at present known A. obtusa 

 is exclusively South African. 



Triton Klenei A. Adams ? (MS.). As the species bearing this 

 name in various collections seems never to have been 

 described I give the following diagnosis : — 

 T. testa ovato fusiformis, utrinque acuminata, luteo fusca, rufo- 

 fusco picturata ; spira elongata, gradata : anfractus 7, valde 

 convexi, angulati, spiraliter granoHrati, longitiidinaliter 

 plicati ; anfractus penultimus plerumqtie unwaricosus ; idti- 

 inus gibbosus, varicibus duabus leviter complanatis et fimbria- 

 tis munitus. Apertura ovata, fauce purpureo-fusco tincta, 

 peristoma album, canali breviusculo vix recurvo. 

 Long. j8 mill. ; maj. diam. 26 mill. ; apert. longa. IJ mill. ; 

 lata. 10 mill. Allied to T. cutaceus. 



T. cutaceus Linn. In my note on T. africatius (J. C, v., 

 Jan., 1886, p. 9), I expressed the opinion that that species 

 was only a modification of T. doliarius.*' I am now of 

 opinion that both are varieties of the Linnean T. cutaceus, 

 so common in the Mediterranean. Mr. Ponsonby has 

 shewn me an undoubted specimen of that species from 

 Port Elizabeth. 



Coralliophila nodosa A. Adams (Latiaxis). Several speci- 

 mens of this somewhat rare Australian species have been 

 collected at Port Elizabeth. 



* Kiener (Iconog. Triton, p. 41, 42) says T. doliarius is only a variety 

 of T. cutaceus. Krauss, p. 114, thinks otherwise.
