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 Bruné and destroyed that piratical 
stronghold. 
4a. CYCLOPHORUS COCHRANE, var. OCHRACEUS. @%/953 
In this variety from the Busan Hills the only difference 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.

, 19%. CYCLOPHORUS TALBOTI, hi. 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 columellar 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. 
mm l48? 6. CycLOPHORUS 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 23 have been formed ; 
aperture circular, suboblique; peristome simple, slightly reflected.
