 albis pieta, lineis incrementi tenuissimis striiscjuc spiralibus obsoletis 

 sculpta ; spira convexe conoidea, ad apiccm obtusa ; anfractus 7, 

 convexiusculi, Icnte crescentes, superne ad suturam linea cornea 

 submarginati, ultimus antice ascendens ; apertura ovata, supra acumi- 

 nata et sinuata, longit. totius ^ paulo superans ; peristoma album, 

 incrassatum, expansum ct reflexum, marginibus callo crasso junctis.

Sah. — Oman. 



This species is well characterized by the strong white continuous 

 lip, the small sinus at the upper end of the aperture, and the style of 

 colouration. The opaque white stripes do not extend downwards be- 

 yond the middle of the body- whorl, excepting as the lip is approached. 

 Ji. StM/diamis, Martens, from Turkestan, is allied to tliis species, but 

 differs in its form and in the peristome. I have associated with this 

 species the name of Dr. F. Jousseaume, who has written important 

 papers on the fauna of Arabia and adjacent localities.^ 



4. BuLiMiNus iNsuLAEis, Ehrcnbcrg. 

 Jlab. — Oman. 



Common in Arabia, India, Ceylon, Afghanistan, Assab, Massoua, etc. 



5. Melania tubekculata, Miillcr. 



Two varieties of this species were collected by Dr. Jayakar, one of 

 a pale greenish tint with or without red spots, and the other of a 

 dark purplish black. Some specimens are paler than others, and in 

 these the red spotting is noticeable, and a dark basal zone is seen upon 

 the lower part of the body- whorl. 



6. Melania ELEGAjsrs, I3cnson, 

 Jlab. — Oman. 



On comparing the specimens from this locality with Eenson's 

 type of this species, presented to the Museum by the late Mr. 11. 

 MacAndrew, I can discover no differences to separate them. 



7. LiMN.EA Arabica, n.sp. Fig. 3. 



Testa angusta, superne acuminata, cornea, ad apiccm rufescens, et 

 infra suturam zona pallida angusta marginata ; spira acuta ; anfractus 

 4 celeriter accrescentes, primus minimus convexus, ca^teri minus 

 convexi, sutura obliqua sejuncti, striis incrementi sculpti, ultimus 

 peroblique descendens ; apertura inverse auriformis, elongata, sub- 

 rufescens ; columella obliqua, in medio contorta et incrassata, callo 

 tcnui labro juncta. Longit. 17*5 mm., diam. 8. Apertura IU'5 

 longa, 5 lata. 



Jlab. — Oman. 



This species is very like certain forms of Succinea, having a narrow 

 and acuminate spire and a very long body-whorl. In general appear- 

 ance it recalls a small form of the Indian L. rufescens, Gray.
