strongly iiodiiled ribs of the angle of the whorl. The mouth is 

 oblong, outer lip thin ; perhaps neither specimen ^\e have seen is full 

 grown, as the sinus is so very obscurely marked. Of much the same 

 form as D. philotima, Melv., from the same seas, but with more 

 produced canal. It resembles a small Latmis, or even a Fasciolaria 

 in miniature, but, of course, there is no columellar plication.

Mangilia ANARiTHMA, n.sp. PI. XI, Fig. 12. 



M. testa parva, ovato-fusiformi, pallide straminea, nequaquam 

 aiigulata, anfractibus ad 6, quorum duo apicales Iseves, globulosi, 

 tertius arete longitudinaliter liratulus, eaeteris tribus longitudinaliter 

 pauci-costatis, costis irregularibus, incrassatis, spiraliter rudiliratis, 

 liris distantibus supra, versus basim magis numerosis, apertura 

 oblonga, labro tenui, sinu fere evanido, canali brevi, lato. Alt. 4-25, 

 lat. 1"50 ram. 



Ilab. — Mekran Coast, Charbar, 40 fathoms. 



Of the same alliance as M. ph(ea, M. & St., which differs in its 

 swarthy brown hue, and in its rarer spiral lira3, particularly on the 

 body-wliorl.

Hai. — Mekran Coast, Charbar, 7 fathoms (Townsend) ; Persian 

 Gulf (Colonel Pelly in Mus. Brit.). 



A select species of a curious waxen grey or olive hue, thickly 

 longitudinally ribbed, and obscurely but closely transversely striolate. 

 The nuclear whorls, three iu number, are glossy and smooth ; the 

 next beautifully longitudinally obliquely ribletted and decussate, in 

 a similar way to M. gracilenta^ lleeve, Portia, Smith, and others of 

 a very closely allied confraternity. This species, however, M. recta, 

 seems to possess peculiar characteristics in its facies, and to be a very 

 good species. 



Mangilia clarisculpta, n.sp. PL XI, Fig. 14. 



M. testa parva, delicata, alba, fusiformi, rugosa, anfractibus ad 6, 

 quorum apicales duo globosi, Iseves, tertius Isevis, unicarinatus, cseteris 

 ad mediam peripheriam angulatis, longitudinaliter nodosi-costatis, 

 costis crassiusculis, infra suturas superficie planata, eleganter tornatula, 

 ultimo versus basim multum attenuato, multilirato, apertura lata, 

 sinu lato, labro incrassato, columella fere recta. Alt. 4, lat. r20 mm. 



ILah. — Mekran Coast, Gulf of Oman, Charbai', 40 to 150 fathoms. 



A conspicuouslv sculptured Mangilia, which would claim close 

 kinship with M. Smithii, Xevill,' from Ceylon. It seems to differ in 

 being slightly larger, with one or two tornate spiral keels just below
