longitudinalibus supra nodosis et paulo infra suturam const rictis, 

 in medio angulatis instruct!, inter costas Iseves, ultimus penultimo 

 vix latior, costis versus labrum tenue sensim evanidis, tuberculis 

 infra suturam solum manentibus, circa basin liris paucis instructus ; 

 apertura parva, longit. totius \ suba^quans ; columella infra recti- 

 uscula, callo Isevi tenui induta, antice callo spirali intrante 

 instructa. 

 Longit. 12 millim., diam. 7 ; apertura 4 longa, 3 lata. 



Hah. Off Colombo, 597 fath. ; also off Kistna coast, 

 753 fath. 



The name diluta has reference to the absence of colour- 

 markings. 



18. Columhella {Mitrella) supraplicata. 



Testa ovato-fusiformis, pallide roseo-fuscescens, nitida ; anfractus 

 normales 7 ?, leviter convexiusculi, superiores quatuor plicis 

 arcuatis tenuibus obliqiiis instrncti, inferiores 2-3 baud plicati, 

 lineis incrementi tenuissirais striisque spiralibus tenuibus sculpti, 

 ultimus antice oblique sulcatus ; apertura angusta, concolor, 

 longit. totius | baud acquans ; labrum arcuatum, extra incras- 

 satum, intus liris brevibus albidis circiter duodecim armatum ; 

 columella obliqua, curvata, callo crassiusculo induta, intus tuber- 

 culis 2-3 munita ; canalis anterior brevis, obliquus. 



Longit. 13 millim., diam. 5 ; apertura 5 longa, 2 lata. 



Hab. Station 232, off Travancore coast, in 430 fath. 



A single specimen. This species in some respects resembles 

 C. Pacei'^y but differs in its somewhat more robust form, in 

 colour, the presence of longitudinal riblets or plica? upon the 

 upper volutions, the thicker ridge-like callus upon the colu- 

 mella, and the somewhat less pronounced labral varix. The 

 spire is less tapering and the whorls are not so turreted and 

 have not the upper edge marginated by a spiral groove. 



19. Coralliophila indica. 



Testa breviter fusiformis, alba, costis longitudinalibus circirer decern 

 et liris transversis squamosissimis (squamis supra costas pro- 

 ductis) instructa; anfractus normales quatuor, supra medium 

 angulati, superne oblique tubulati, infra leviter convexi, squamis 

 supra costas ad angulum ceteris longioribus sursum erectis, 

 ultimus infra medium contractus, antice breviter caudatus et 

 rimatus ; apertura piriformis, antice canaliculata, cum canali 

 longit. totius | paulo superans ; columella rectiuscula, callo
