impressa obscura pauliilum infra suturam eincti ; anfr. ultimus 

 quadratus ad peripheriam zona angusta alba cinctus. 

 Long. 17 mill,, diam. 4.

The above is probably the description only of the young 

 state of a largish 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. 



Terehra tricincta^ sp. nov. 



Testa parva, subulata, nitida, cornea ; anfract. 14, primi 4 politi, 

 convexi, caeteri medio concavi, cingulis 3 nodulosis (supremo 

 maximo cingulum infrasuturale constituente, medio minimo 

 supremo fere contiguo, infimo prope suturam) eincti ; noduli 

 costis longitudinalibus numerosis graciUimis (in anfr. ultimo 17-20 

 basi contiuuis) connexi ; anfr. ultimus quadratus ad peripheriam 

 liris 3 nodulosis et basim versus altera simplici cinctus ; columella 

 inferne oblique contorta, eallo tenui livido labro juncta ; canalis 

 brevis, latus. 



Long. 11 miU., diam. 2|-. 



Hah. Persian Gulf [Colonel Pelly). 



The uppermost of the three nodulous belts which encircle 

 the 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. 



Terehra persica, sp. nov. 



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

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

 vexi, cseteri medio concavi, costis longitudinalibus numerosis (in 

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

 (nodulis superioribus majoribus cingulum infrasuturale partim 

 constituentibus) instructi, et lirulis spiralibus super costas con- 

 tinuis 3-4 eincti ; cingulum (in cochleis detritis supra nodulos 

 obsolete) crebre striatum ; sutma profunda ; anfr, ultimus qua- 

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

 columella brevis, basi oblique contorta ; canalis latiusculus, leviter 

 recurvus. 



Long. 12 mill., diam. 3, 



Hah. 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 examples which I have examined, is quite 

 different from that of any other species. The fine striation.is
