MELVILL : GASTROPODA FROM THE PERSIAN GULF, ETC. 167 



suggested by the beautiful spiral row of shining gcmmjB more par- 

 ticularly decorating the upper of the spiral keels so prominent ou 

 the whorls. 



Mangilia Koweitensis, n.sp. PI. X, Fig. 23. 



M. testa anguste fusiformi, minuta, solida, pallida straminea, 

 anfractibus 6, quorum apicales duo albo-vitrei, laeves, tertio longi- 

 tudinaliter multilirato, aliter Isevi, nitido, caeteris longitudiualiter 

 costatis, costis rectis, ultimum apud anfractum circa 12, apud basim 

 evanidis, undique spiraliter pauciliratis, liris crassis, ad juncturas 

 costarum gemmatis, apertura anguste oblonga, labro percrasso, albo, 

 supra obscure unidenticulato, columella fere recta, canali brevi. Long. 

 4-15. lat. 2 mm. 



Hah. — Koweit, Persian Gulf, 10 fathoms. 



A Cytharoid little species, elegantly formed. Some slight analogy 

 with M. Fairbanki, Nevill, or obeliscus, Reeve, exists, but our 

 specimens are in every way adult, and much smaller. Baphnella 

 arcta, E. A. Sm., from the same locality, is also to same extent 

 comparable. 



Daphnella bea, n.sp. PI. X, Fig. 24. 



D. testa delicata, tenui, albida, ventricosa. fusiformi, anfractibus 

 8-9, quorum apicales 4 ochracei, pulchre decussati, apice ipso vitreo, 

 Isevi, cseteris inflatis, undique pulcherrime et arctissime deeussatis, 

 liris longitudinalibus tenuissimis, obliquis, apertura oblonga, labro 

 effuso, tenui, sinu obscure, canali brevi. Long. 11, lat. 4 mm., 

 sp. max. 



Most exquisite in decussating sculptui'e of the finest character ; 

 a thin, almost colourless, and inflated shell, its outer lip hardly 

 exhibiting any sinus. This species is finer-grained than the nearly 

 allied B. thia, M. & S., from the same locality, and of different form 

 to the also closely akin B. huccinulum, M. & S. 



Daphnella Lucasii, n.sp. PI. X, Fig. 25. 



D. testa inflata, fusiformi, tenui, parum nitida, obscure brunneo- 

 maculata, anfractibus 9, quorum apicales 4, apice ipso parvo, tribus 

 huic proximis sub lente pulcherrime decussatulis, caeteris valde ventri- 

 cosis, spiraliter distincte acutiliratis, liris apud penultimum 7, ultimi 

 anfractus 18, intervallis imparibus, undique irregulariter longitudiua- 

 liter lirato-costatis, costulis ad ultimum. perssepe evanidis, apertura 

 rotundo-ovata, labro tenuissimo, effuso, canali paullum recurvo, paullum 

 producto. Long. 10, lat. 4'50mni. 



The conspicuous spiral Urge extending at unequal intervals over the 

 whole surface of the lower whorls, almost unbroken oh the ventricose 

 body-whorl, while crossed frequently above by irregular liral riblets 

 on the upper whorls, distinguish this little Baphnella from its con- 

 geners. It is slightly like B. teres, Forbes, in general form, or 

 B. mannorata, Hinds. I have pleasure in connecting with it the
