 The southern Ebukna. Shell ovate, imperforated, 

 spire rather short, sutures broadly depressly chan- 

 nelled, sculptm-ed at the base with five or six light 

 gi-ooves, then with a single rather deep one, above 

 striated with fine punctures, whorls five in number ; 

 yellowish white, with a row of red-brown spots next 

 the sutures, and a very few smaller ones beneatli.

The Eburna australis has been confounded by many 

 authors with the Cancellaria spirata of Lamarck, bcUeviug 

 them to be identical. M. Deshayes goes so far as to say 

 that Mr. Sowerby has represented the same shell in two 

 places (Conch. Illus. Cancellaria, f. 25 and Eburna, f. 5.), 

 suiting the configui'ation of the columella in each instance 

 to the character of the genus. Such is not the case. The 

 tliree-plaited Cancellaria spirata and the Eburna aiisfralis 

 are two veiy distinct shells, the latter being of more solid 

 growth, smooth towards the apex, and furnished with an 

 arched callous columella, characteristic of the genus to 

 which it has been referred in the absence of any more 

 suitable place. 



Species 5. (Mus. Cuming.) 



Kburna ambulacrum. Eburn. testa ovatd, umbilicatd, 

 spira Huturis profundi canaliculalis, anfractibus sub- 

 plano-convexis, lavibus ; albidd, fuscescente-spadiceo 

 creberrime maculatd et nclmlato-tiiictd, apici; niyri- 

 cante. 



The gallery Eburna. Shell ovate, umbilicatcd, sutures 

 of the spire deeply channelled, whorls rather flatly 

 convex, smooth ; whitish, very closely spotted and 

 clouded with brownish bay, ape.\ blackish. 



Sowerby, Tankerville Catalogue, App. p. xxii. 



Hub. Isle of Mindanao, Philippines (in sandy nmd at the 

 depth of twelve fathoms); Cuming. 



Very closely allied to the E. spirata, but always readily 

 distinguished by its smaller size, darker colour, and more 

 closely clouded spots. 



Species 6. (Mus. Cuming.) 



Eburna abeolata. Ebum. testa ovato-ventricosd, spird 

 elevatd, profundi et ampliter umbilicatd, convexis, 

 lavibus, superne obtuse depresses, stchcanaliciilatis, vix 

 angulatis ; albd, macnlis rufo-ca,staneis graiidibus ob- 

 longo-quadratiis subundatis seriatim ciiictd. 



The square-spotted Eburna. Shell ovately ventricose, 

 spu-e elevated, deeply and largely umbiMcated, convex, 

 smooth, obtusely depressed round the upper part, 

 slightly channelled, scarcely angidated ; white, en- 

 circled with rows of large oblong-square slightly 

 waved reddish-chestnut spots.

 Buccinum spiratum var., Bruguiere. 

 Eburna tessellata, Swainson. 



Hub. Ceylon. 



The spots are disposed in three rows, the lowest being 

 concealed in all but the last whorl, by the superposition 

 of one whorl upon the other. 



Species 7. (Mus. Cuming.) 



Eburna spirata. Eburn. testa ovatd, parum umbilicatd, 

 spird acutd, suturis profundi canaliculatis, anfractibus 

 subplano-convexia ; albd, fulvescente-spadiceo viaculatd, 

 maculis medianis minoribus, apice cdBrideo-uigricante. 



The spiral Eburna. Shell ovate, but little umbilicated, 

 spire sharp, sutures deeply channelled, whorls rather 

 flatly convex ; white, spotted mth fulvous bay, 

 middle spots the smaller, apex bluish black.

Uab. Ceylon. Philippines. 



An interesting variety of this well-known species was 

 collected during the voyage of the Samarang, in which 

 the spots were smaller and of much darker coloui'. 



Species 8. (Mus. Cuming.) 



Eburna Zeylanica. Eburn. testa ovato-cotiicd, profundi 

 et ampliter umbilicatd, spird acuminatd, suturis nun-

 gatis ; alia, maculis grandibus simtalis fuho-spadicek
