75-1 MR. G. B. SOWERBY ON NEW SHELLS. [Nov. 21, 



arranged in three bands ; spire acute, short, whorls concave, nearly 

 smooth, last whorl biangulated. 



This interesting little Cone belongs to the rich collection of Dr. 

 Prevost, ofAlencon. Apart from its somewhat stunted form, the 

 delicacy of its markings and rows of gem-like granules, it is remark- 

 able for the double angle at the top of the body-whorl. 



Conus reflectus, sp. nov. (Plate LXXV. fig. 6.) 



C testa pyriformi, antice granulala, postice Icevi, ad angulum 

 minutissime coronata, albida, roseo late bifusciata, fasciis fusco 

 nebuhitis ; spira modica, anfractibus concaviusculis crebre sul- 

 catis ; apice acuminato. 

 Long. 25, fat. 15 mill. 



Shell pear-shaped, anterior portion granulated, otherwise smooth, 

 very minutely coronated at the angle, whitish, with two broad bands 

 of rose-colour clouded with brown ; spire moderate, whorls rather 

 concave, closely grooved ; apex acuminated. Specimen in the col- 

 lection of Dr. Prevost. 



Lima zealandica, sp. nov. (Plate LXXV. fig. 1 a, fig. 1 b.) 



L. testa lata, crassa, subinjlata, radiatim costata, utrinque pau- 



lulum hiante ; latere antico oblique producto, late concuvo- 



planulato, infra medium angulato, margine ventrali ad angulum 



acclivi; latere postico oblique rotundato ; costis 18, regulari- 



bus, quadrutim rotuudatis, crassis, squamatis, interdum fulvo- 



rubescentibus ; interstitiis Icevibus, concavis, costas cequantibus ; 



auriculis parvis declivibus ; umbonibus acutis incurvatis. 



Shell broad, thick, rather inflated, radiately ribbed, slightly gaping 



on each side ; front side obliquely produced and concavely flattened, 



forming an oblong lunule terminating below the middle in a decided 



angle ; the other side obliquely rounded ; ribs eighteen in number, 



rather square, thick, scaled, sometimes of a reddish-brown colour ; 



interstices between the ribs smooth, concave, equal in width to the 



ribs ; auricles small, sloping ; umbones acute, incurved. 



Hab. New Zealand. 



This species is well distinguished from its congeners by a broad 

 concave lunule, forming a straight outline to one side of the shell, 

 terminating in an abrupt angle. Among recent species its nearest 

 analogues are L. paucicostata (Sowerby) from the Red Sea, and L. 

 multicostatu (Sowerby) from Australia ; but it differs from both these 

 in the characters above mentioned, and in the number of ribs being 

 more than those of the former and less than those of the latter ; the 

 ribs also are more elevated than either. There is a fossil species found 

 in the Pliocene of New Zealand to which this is more nearly allied ; but, 

 upon comparison, I am convinced that it is distinct. All the species 

 of Lima hitherto known being entirely white (with the exception of 

 L.fasciata, which has very faint fulvous concentric bands), receiving 

 first the coloured specimen of the new species I thought the colour 

 might prove specific ; but I have since received a larger specimen in 

 which there is no trace of colour; so that the coloured specimen
