1889.] LAND-SHELLS FROM BORNEO. 335 



surface with ordinary lines of growth ; colour a pale ochre ground, 

 mottled somewhat sparsely with dark liver-brown, below the keel 

 with stronger zigzag blotchings ; spire conoid, rather high ; apex 

 subacute ; suture shallow ; whorls 5, the last flattened on the side ; 

 aperture circular, suboblique ; peristome continuous, simple, slightly 

 reflected, sinuate below the columellar margin and with a slight 

 thickening there. 



Size: maj. diam. 41, min. 32*5 ; alt. axis 18"0 millim. 



Hab. Busan and Niah Hills {A. Everett). 



There are three specimens in the collection, one being from the 

 Niah Hills. 



I have named this fine species after Rear-Admiral Sir Thomas 

 Cochrane, who commanded the combined squadron in the Bornean 

 waters in 1846, which captured Brune and destroyed that piratical 

 stronghold. 



4a. CyCLOPHORUS COCHRANEI, var. OCHRACETJS. ii'JhJiffl 



In this variety from the Busan Hills the only difi^erence observable 

 in the form of the shell is its deeper suture. It has no markings of 

 any kind, the whole surface being of a dark straw or ochre colour. 

 There are two specimens, and as they are from the same hills I do 

 not think they can be separated from the species above described. 



^ ?^M '•' ^- CyCLOPHORUS TALBOTI, U. Sp. 



Shell turbinate, subangulate ; umbilicated, but umbilicus nearly 

 hidden by the reflection of the columellar margin of the aperture ; 

 colour rich madder-brown, paler around the umbilicus, in one speci- 

 men a dark band below the periphery, speckled with white and with 

 a regular series of pale whitish ochre spots following the suture, a 

 line of similar smaller spots on the keel ; spire conic ; apex subacute ; 

 suture moderately impressed ; whorls 5, convex; aperture circular, 

 oblique ; peristome solid, simple, slightly reflected, very sharply so 

 on the columell.ir margin. 



Size: maj. diam. 40, min. 22*5; alt. axis 17"0; diam. body- 

 whorl 23-25 millim. 



Hab. Busan Hills (A. Everett). 



This species is allied to C. borneensis, but is not so openly um- 

 bilicated or so sharply keeled, and the apical whorls increase in size 

 more rapidly ; the coloration is much darker and more attractive. 

 I have named it after Captain Talbot, who commanded H.M.S. 

 'Vixen,' and in 1845 defeated and took the stronghold of Sheriff 

 Osman in the Mulludu river. 



, ifl<3 6. Ctclophorus phlegethon, n. sp. 



Shell depressedly turbinate, subangulate on periphery, openly and 

 widely umbilicated ; sculpture a smooth surface ; colour a rich dark 

 madder-brown, crossed by fine zigzag continuous pale lines ; spire 

 low ; apex blunt and rounded ; suture impressed ; whorls 4, at apex 

 closely wound, and increasing rapidly after 2k have been formed ; 

 aperture circular, suboblique ; peristome simple, shghtiy reflected.
