 Loug, 17 mill., diani. 4. 



Hub. Cape Siina, .Tajxin {Coinmatuler St. John). 



Tlie above is probably the description only of the young 

 state of a hirgisli species ; but the characters are so distinc- 

 tive that it is not, I think, very hazardous to describe it. The 

 black apex, the smooth whorls, the white zone dotted with 

 chestnut below the suture, and the narrow white band round 

 the last whorl easily define the species. 



Terebra tricincta, sp. nov. 



Testa parva. su])ulata, nitida, cornea; anfract. 14, primi 4 politi, 

 convexi, caiteri medio concavi, cingulis 3 nodulosis (supremo 

 maximo cingulum infrasuturale constituente, medio mini mo 

 supremo fere contiguo, infimo prope suturam ) cincti ; noduli 

 costis longitudinalibus numerosis gracillimis (in anfr. ultimo 17-2U 

 basi continuis) eonnexi ; anfr. ultimus quadratus ad peripheriam 

 liris 3 nodulosis et basim versus altera simplici cinctus ; columella 

 inferne obli<iue coutorta, callo tenui livido labro juncta ; canalis 

 brevis, latus. 



Long. 11 mill., diam. 2^. 



llah. Persian Gulf {Colond Pelhj). 



The uppermost of the three nodulous belts which encircle 

 tlie whorls is considerably the largest ; the intermediate one 

 is merely a fine spiral liration, nodose at those points where it 

 is crossed by the thin longitudinal ribs. 



Terebra persica J sp. nov. 



Testa parva, subulata, nitida, corneo-albida, versus apicem et 

 anfract. ultimi basi purpurasccns ; anfr. 13?, primi 3 politi, con- 

 vexi, cseteri medio conca\-i, costis longitudinalibus numerosis (in 

 anfr. ult. 15-20 ad basim attenuautibus) utrinque nodulosis 

 (uodulis superioribus majoribus cingulum infrasuturale partim 

 constituentibus) instnicti, ct lirulis spiralibus super costas con- 

 tinuis 3-4 cincti : cingulum (in cocbleis detritis supra nodulos 

 obsolete) crebre striatum; sutiu-a profunda; anfr. ultimus qua- 

 dratus, ad peripheriam liris 3 cinctus, inferne teuuitcr striatus ; 

 columella brevis, basi oblique coutorta ; canalis latiusculus, leviter 

 recurvus. 



Long. 12 miU., diam. 3. 



Hab. Persian Gulf {Colonel Pelly). 



Possibly the above may not be the dimensions of a full- 

 grown specimen ; but the style of the sculpture, which is con- 

 stant in the twelve examjdes which I have examined, ia quite 

 different from that of any other species. The tine striation.'j
