1881.] MR. G. B. SOWERBY, JTJN., ON NEW SHELLS. 637 



Resembling the Chinese C. siriatus in form, but a much smoother 

 shell than any of that species that I have met with (and I have seen 

 some hundreds) ; and it is more deepl)' coloured ; but the chief 

 difference is in the crown. C. sulcatus is characterized by a sharp 

 undulating keel at the angle, forming a raised ridge rouud the de- 

 pressed whorls of the spire ; while in C. bocki the crown is formed 

 of slightly angular nodules, between which the angle is rounded. 



I have seen only a single specimen of this interesting shell, which 

 was brought by Mr. Carl Bock from the above-named locality, and 

 is now in the collection of Dr. Prevost. 



4. CoNUS GLOYNEi, n. sp. (Plate LVI. fig. 5.) 



Testa abhreviato-turhinata, solida, castanea, brunneo late bifasciata ; 

 spira abbreviata, conica, brunnea ; anfractus superne leviter con- 

 cavi, spiraliter profunde trisulcati ; anfr. ultimus ad unguium 

 leviter coronatus, infra unguium levissime convexus, laviusculus, 

 vel minutissime striatus, basin versus valide costatus; apertura 

 angustu, ulbidu ; labrtim ad unguium leviter emarginatum. 

 Long. 26, diam. 16 miUim. 



Hub. 1 



A short brown Cone of no very striking character, excepting per- 

 haps that the grooves of the spire are unusually deep. Although 

 of ordinary appearance, I cannot identify it with any known species. 

 The shell was given me by Mr. C. P. Gloyne, who had no iutbrma- 

 tion as to its habitat. 



5. CoNus LOMBEi, n. sp. (Plate LVI. fig. 6.) 



Testa conica, solidiuscula, rufo-fusca ; spira acuta, subgradata ; 

 anfractus superne declives, l<evi, ungulati, ad unguium maculis 

 albidis numerosis ornuti ; unfr. ultimus superne subacute anyu- 

 lutus, ad latera prope rectus, Icevigatus, busin versus oblique sul- 

 cutus ; apertura ungusta,fauce purpurea ; labrum ad unguium vix 

 emarginatum. 

 Long. 22, diam. 10 millim. 

 Hub. Mauritius 1 



A small reddish-brown Cone, with a purple interior, and white spots 

 on the angle and spire, giving it a coronated appearance, although 

 the angle is free from nodules. 



The specimen which is now in the British Museum was in the 

 collection of the late Thomas Lombe Taylor, with a label " Conus, 

 nov. sp,, Mauritius." As the labels of that collection were loose, 

 and many of them got shifted, the habitat assigned to this species 

 is very uncertain. 



6. Cancellaria wilmeri, n. sp. (Plate LVI. fig. 2.) 



Testa oblonga, ucuminutu,fusca ; anfractus 7, convexiuscuU, superne 

 anguste excuvati, costis 7iumerosis noduliferis et liris transversis 

 cuncelluti ; spira elutu ; uperturu oblongo-ovuta, fusca ; labrum 

 concave depressum, urcuutum, superne emarginatum ; columella 

 curta, rectiuscula, minute triplicatu.
