4 Dr. J. C. Melvill on Marine MoUusca 



feuestrato, ultimo bicarinato, infra suturas radiatim oblique 

 decorate, carinis marpinatis, apud basin spiraliter qninque-lirato, 

 liris circa umbilioum fcnestratis longitudinaliter incrassatulis ; 

 npertura rotunda, iutus pulchre iridescente, peristomate tenui. 

 Long. 5, lat. 8 mm. 



Hub. Persian Gulf. 



A unique and most beautiful species. From tlie fi^^ure 

 and description, fo near does it appear to Muniha trajyicalis, 

 Hediey *, from ^last Head Reef, Queensland, that I place it 

 in the same genus ; otherwise I had considered it, periiaps^ an 

 Eumargarita^ P. Fischer. Some authors, doubtless, would 

 include it in Solariella, S. Wood, but this last is but sub- 

 generic to Monilea, in my opinion. 



Epitonium schepmani, sp. n. (PI. I. fig. 6.) 



E. testa late ovata, delicata, alba, vel albo-cinerea, imperforata ; 

 anfractibus 9, quorum apicales tres bicolores, nitidissimi, per- 

 Iseves, caeteris veutricosis, apud suturas impressis, longitudinaliter 

 undique lamellosis, lamellis bic illic varicosis, tenuibus, laevibus, 

 fragilibus, anfractibus supernis arctissime lamella! is, anfractu 

 ultimo bi- vel trivaricoso, lamellis ad 36, interstitiis inter lamellaa 

 spiraliter delicato-striatis ; apertura rotunda, peristomate con- 

 tiuuo, margine columellari incrassato. 



Long. 9, lat. 4-50 mm. 



Bab. Siieikh-Shualb I., Persian Gulf. 



Distinguished hy its thin, shining, smooth lamellse, which 

 are so crowded in the two or three whorls just below tiie nuclear 

 as almost to impinge upon each other. They number thirty- 

 six upon the body-whorl, of these two or three are variced. 

 It does not seem very akin to any of the Scalarice known 

 from the Persian Gulf region. 1 have much pleasure in 

 dedicating this interesting species to Dr. M. M. Schepman, 

 whose monograph on the Gastropodous MoUusca of the 

 ' Siboga ' expedition is memorable. 



Epitonium zairephes, sp. n. (PI. I. fig. 5.) 



E. testa oblonga, imperforata, delicata, albida ; anfractibus 9, quorum 

 tres apicales laeves, nitidi, caeteris ventricosis, apud suturas im- 

 pressis, lamellis tenuibus ornatis, numero anfractum ad ultimum 

 circa 20, anfractibus supernis arctissime lamellatis, interstitiis 

 inter lamellas pulcLre et arcto striatis ; apertura fere rotunda, 

 peristomate continuo, columella paullum excavata. 



Long. 9, lat. 4 mm. 



Hub. Mekran Coast ; off Charbar.
