18 ZOOLOGY OF THE VOYAGE OF H.M.S. SAMAKANG. 



overlooked by Mr. Hinds in describing the Mollusca of that expedition. It had unfortunately 

 no memorandum of its locality. 



The upper portion of the whorls is sharply angled, and distinguished by a row of fine 

 obliquely disposed nodules, the interstices between which are stained with the same rusty 

 brown colour with winch the rest of the shell is bedaubed. The apex is papillary. 



2. Conus Borneensis. PL V. Pig. 8 a, b, c, d. Con. testa fusiformi, medio attenuate, spira acute 

 elevata, anfractibus superne concavis et angulatis, infra transversim lineari-sulcatis, sulcis setate plus minusve 

 obsoletis, longitudinaliter lineis incrementi arcuatim striatis ; alba, rufo-fusco sparsim maculata. 



Hab. North-east coast of Borneo (in ten fathoms, sandy and stony bottom). 

 The main distinction between this species and the C. arcuatus, to which it is so closely 

 allied, consists in its attenuated growth, a character satisfactorily observed by a careful 

 comparison of several specimens with the type of that species in Mr. Cuming's collection. 



3. Conus flokidulus. PL V. Pig. 9 a, b. Con. testa oblongo-turbinata, solidiuscula, basi tumidiuscula, 

 liris perpaucis subdistantibus, spira striata, obsolete oblique coronata, apice acuta; violascente-alba, basi 

 vivide roseo-violacea, medio fasciatim immaculata, snpra infraque aurantio-fusco tincta et punctata, apice 

 pallide rufescente. 



Hab. ? (from the Sulphur Voyage). 



A shell of rather solid growth, very deeply stained with violet at the base, and delicately 

 suffused with that colour throughout ; a pale band being formed round the middle by the 

 interruption of the orange-brown dots, which are painted above and below it. The spire is 

 very indistinctly undulately noduled, and faintly spotted with orange-brown, with which" 

 colour it is also tinged at the apex. 



4. Conus pica. PL V. Pig. 10 a, b, c, d. Con. testa sub-cylindraceo-ovata, tenuicula, tumida, inflata, 

 spira depresso-convexa, creberrhne impresso-sulcattL, apice parvo, acute elato ; basi lineari-suleata, sulcis 

 subdistantibus ; alba, fusco-nigricante plus minusve grandimaculata et minute punctata. 



Hab. Island of Balambangan, north end of Borneo (on a shallow coral reef). 



Very closely allied to the C. spectrum, but distinct in form and style of painting. 



5. Conus pigmentatus. PL V. Pig. 11 a, b. Con. testa oblongo-turbinata, transversim obsolete 

 crebrisulcata, spira striata et oblique coronata ; alba, violascente tincta, olivaceo maculata, flocculis albis 

 hie illic aspersa, basi et aperturse fauce vivide caeruleo-violaceis, spira alba, apice intense roseo. 



Hab. ? (from the Sulphur Voyage). 



An extremely interesting species in which the apex is remarkable for its intense crimson- 

 rose colouring in all stages of growth. The ground colour is a pale verdigris blue, the shell 

 is then crossed by olive lines which form two broad bands, and these are sprinkled with 

 little opake-white flakes ranging mostly in a longitudinal direction, and the crimson apex 

 rising in the centre of a pure white spue is very conspicuous. The interior is a rich violet.
