feeble ; left valve with two divergent cardinals, the anterior stouter 

 and triangular; a large lamelliform and marginal lateral tooth is 

 present, which is connected above with the posterior cardinal, the 

 anterior lateral much less distinct, elongated and distant. Ligament 

 very short. The adductor scars are oval, distinct, the anterior deeper. 

 I'allial line simple and entire. Length 9, height 8, diam. 4*5 mm. 



Hah. — A number of valves were obtained by Captain J. Bollons in 

 18 fathoms, Port Pegasus, Stewart Island. A few valves were also 

 gathered by Mr. A. Hamilton when dredging off Otago Heads. 



Type in my collection. This species is nearest related to our 

 V. corhis, Phil., and V. Infea^ Hutton. The former is usually much 

 smaller, shorter and more triangular, with 10 to 11 costse, broader 

 than the interspaces. V. hitea is sometimes found twice as large, but 

 by comparing specimens of the same size it proves to be more oval, the 

 ribs tiner or more numerous, about 16, interspaces narrower than the 

 ribs, inside brown. 



It gives me great pleasure to unite the name of Captain J. Bollons 

 with the species. It is to his great interest in conchology and his 

 indefatigable energy that we owe so many interesting discoveries, and 

 his liberality and readiness in procuring specimens for study are really 

 inexhaustible. 



Tellina (Angulus) Spencekt, n.sp. PI. XYIII, Figs. 9-9 J. 

 Shell elongately oval, thin, compressed, rostrate and but slightly 

 flexuous posteriorly, subequilateral, with fine concentric striae. 

 Peaks small, approximate, sharply pointed, smooth and shining, 

 a little anterior. Anterior end regularly rounded, nearlj" straight 

 dorsally, with a sliglit fold from the beaks to a little above the middle. 

 Posterior end rostrate, with a distinctly raised fold from the beaks 

 towards the posterior angle, slightly flexed to the right ; the dorsal 

 margin excavate below the ligament, descending straight to the 

 rostrum, and slightly sinuate below it. Basal maigin broadly 

 rounded, somewhat straightened in the middle. Sculpture consists 

 of close and fine concentric striae with distinct periods of rest ; the 

 striae are more distinct and slightly raised on both ends, inconspicuous 

 in the centre. Very faint and distant radiate lines are visible uuder 

 a good lens. Epidermis very thin, light yellowish, easily rubbed off. 

 Colour yellowish- white, darker on and above the posterior fold. 

 Interior of valves white, porcellanous ; margins smooth. Hinge : 

 riglit valve with a central triangular and bifici cardinal, a second in 

 front of it, which is a little smaller and oblique ; close and parallel to 

 it is a distinct lateral tooth ; a trace of a posterior lateral is mostly 

 present, situate behind the nympha, the latter being rather short. 

 Left valve with a posterior, thin and very oblique, and a central, 

 trigonal, bifid cardinal. The ligament is rather short and high. 

 Anterior adductor scars oval, posterior scars almost round and larger. 

 Pallial sinus large, broadly triangular, the highest point near the 

 middle of the antero-posterior axis, thence descending to within 

 a short distance of the anterior adductor scar; the ventral part 

 coalescent with the pallial line, which is parallel to the ventral
