the specimens seen by Von Martens, is sometimes entirely wanting, 

 or is replaced by one of a bright orange tint. 



7. LiMICOLAEIA FLAMMEA (Miiller). 



Hah. — Guaso Nai'ok, Alngaria and Leikipia ; also Njenips Indogo, 

 near Lake Baringo. 



Two specimens fi'om the two first of these localities probably belong 

 to this variable shell, which ranges westward to the Gulf of Guinea. 

 It is recorded from the Ukamba region by Von Martens. The single 

 example from Njenips Indogo belongs to the variety dimidiata, 

 Martens, fi'om the Kilima Njaro district. (Conch. Mitth. iii. pi. xliii. 

 figs. 6-7.) 



8. AcHATiNA FiTLVA, Bi'uguiere. 

 Eeeve, Con. Icon. fig. 10. 



Hah. — Near Mkonumbi, Witu, on sandy steppes (Gregory) ; 

 E. Africa (Rve.). 



The two specimens brought from Mkonumbi are not quite adult, 

 and consequently rather thin. The upper whorls are coloured like 

 the shell depicted by Reeve, but the last is of a rich chestnut tint. 



9. SuBULiKA PAucispiRA, Martens. 



Sitz. Ber. naturf. Freund. Berlin, 1892, p. 177. 



Hab. — Eldoma Eavine, south of Lake Baringo (Bishop Tucker) ; 

 Karewia, at the west foot of the Eunsoro Mountains and in the Ituri 

 district (Martens). 



The specimens from the Eldoma Eavine given to Dr. Gregory 

 by Bishop Tucker, agree exactly with examples of this species 

 presented to the British Museum by Prof. E. von Martens from 

 the original locality, Xarewia, where they were collected by 

 Dr. Stohlman. 



10. Stkeptaxis Kibweziensis, n.sp. Eig. 1. 



Testa oblique ovata, perforata, tenuis, subpellucido-albida, epider- 

 mide tenui lutescente induta, nitida, oblique costulata (costulis 

 tenuibus, obliquis, arcuatis, confertis, ad suturam erectis, supra latus 

 ventrale anfr. ultimi evanidis) inter costulas microscopice spiraliter 

 striata ; anfractus 6 convexiusculi, superiores 2-3 laevigati, ultimus 

 oblique valde devians, antice costulatus, latere ventrali polito, sub- 

 planato, prope labrum subascendens ; umbilicus mediocriter angustus, 

 callo circumscriptus ; apertura obliqua, albida ; peristoma leviter 

 incrassatum, ad columellam sublate reflexum, infeme mediocriter 

 effusum, margine externo perobliquo, in medio valde excurvato, 

 superne ad insertionem hand profunde sinuato. Longit. 16 mm, ; 

 diam, 11-5 mm. ; apertura 7 longa, 6'5 mm. lata. 



Hah. — Kibwezi. 



From its form this species might be regarded as a dwarfed specimen 

 of S. Craveni, Smith. It consists of one whorl less, and is differently 

 sculptured. Gonaxis Bloyeti, Bourguignat, is also very similar in 

 form. It is not, however, identical in this respect ; the outer lip is 

 not sinuated and much straighter, and the body-whorl is smoother ; 

 the peculiar circumscription of the umbilicus by a callus is 

 remarkable.
