METULA DAPBNELLOIDES, sp. n. (PI. G. fig. 9.) 

 M. testa eleganter fusiformi, albida, delicata, mitrali ; anfractibus 9, quorum 

 4'i apicales albo-vitrei, lseves, spiraliter circumcarinati, supernis una.inferis 

 duabus carinis prseditis, ceteris apud suturas gradatulis, undique longitudi- 

 naliter pulcherrime et arete costatis (ultimi anfractus ad 46), costis rectis, 

 hevissimis, nitentibus, interstitiis spiraliter liratis, infra, juxta suturas, plica 

 spirali conspicua ssepe pradita, superficie hie il lie obscure stramineo maculata 

 et depicta, ultimo anfractu (11 mm. in longitudine) gracili, paullum producto ; 

 apertura anguste oblonga, intus alba, nitida, labro paullulum effuso, crassius- 

 culo, intus multidenticulato ; columella incrassata, pernitida, simplici, basi lata, 

 Long. 17, lat. 5'50 mm. 



Hob, Gulf of Oman, lat. 24° 58' N., long. 56° 54' E., 156 fathoms. 

 Two species of the genus occurred together, the above being mitriform, 

 elegantly spindle-shaped, and white ; the other is the Buccinum metula, 

 Hinds, = Metula Muihii, Adams and Reeve, which should properly, we 

 consider, be known by the duplicated name of Metula metula (Hinds). This last 

 is larger, with coarser ribs and spiral liration, and does not possess the obscure 

 straw maculations of the M. daphnelloides. 



The apical whorls are well worth examination. Four or five in number, out 

 of a total of nine in all, they are glassy vitreous white, the extreme apex 

 mamillate, small, the next whorl with one keel, the others twice spirally 

 carinate, the remainder of the whorls being closely longitudinally ribbed ; ribs 

 smooth and shining, white, the interstices closely spirally lirate. The mouth 

 and lip of the new form resemble those of Metula hindsii, but are finer and 

 the inner labral denticulations more numerous. 



MUREX (OCINEBRA) MARJORIsE, sp. n, (PI. C. fig. 10.) 

 M. testa sol'da, ovato oblonga, albo-cinerea ; anfractibus sex, undique costatis, 

 costis percrassis, varicosis, sex-fimbriato-squamatis, numero anfractum apud 

 ultimum quinque, ad medium anguliferis, spiraliter squamato-liratis, liris 

 rudibus, crassis ; apertura rotundo-ovata, labro extus pulcherrime multi- 

 fimbriato, albo vel stramineo, crasso, intus nitido, 9 — lC-crenulato, canali 

 brevirostrato, fere clauso. 

 Long. 25, lat. 13"50 mm. 

 Hab. Persian Gulf, Sheikh Shuaib Island, 15 fathoms. 



An exceedingly elaborately frilled species, the fimbria} being thick and 

 squamate, with fluted processes. In form this shell recalls M. coceineus, A. Ad. • 

 the outer lip is either white or straw-coloured, the canal is shortly rostrate, 

 almost closed. M. cyclostoma, Sowb., is a near ally ; we have Erythraean 

 specimens of this, but the form is much more rotund and the fimbriations in 

 no way so elaborate. 



PER1STERNIA CORALLINA, sp. n. (PI. C. fig. 11.) 

 P. testa solida, parva, ovato-fusif ormi, cinereo-albescente ; anfractibus 6, apicali 

 lsevi, simplici, ceteris longitudinaliter crassicostatis, costis paucis, in ultimo 

 apud 7, undique spiraliter rudiliralis ; apertura anguste ovata, pallide
