46 ZOOLOGICAL EESULTS OF THE EUWENZOEI EXPEDITION. 



almost black, oblique flames and short wavy lines of a reddish-brown colour at the 

 upper part of these whorls. In another shell from the same locality these reddish 

 lines extend further over the whorls, in the last of which they cover three-fourths of its 

 extent. I am inclined to think that Martens * has figured this species as L. colorata, 

 vars. s«^Mra#a. and infrafusca, and perhaps ywscescejis. L. mediomaculata Martens-}' 

 is also very closely allied. 



9. HoMORUS FUSCOSTEIGATUS, sp. n. (Plate I. fig. 14.) 



Testa subulata, sordide lutea, strigis obliquis numerosis saturate fuscis picta, ad 

 apicem hand strigata, ad suturam linea lutescente cincta; anfractus 10, lente 

 accrescentes, leviter convexiusculi, lineis tenuibus confertis incrementi striisque 

 spiralibus decussati, ultimus ad peripheriam rotundatus, linea fusca indistincta 

 cinctus ; apertura inverse auriformis, cserulescens, longitudinis totius j fere 

 sequans ; labrum tenue, nigrescens ; columella tenuis, leviter arcuata, antice 

 breviter truncata. 

 Longit. 32 mm., diam. 7^; apertura 7^ mm. longa, 4 lata. 

 a. Mubuku Valley, E. Euwenzori, 7000 feet. 



8uhulina martensi of Dupuis and Putzeys appears to be closely related to the present 

 species, but is much larger, with more convex whorls. 



The lines of growth in H. fuscostrigatus are somewhat puckered at the suture, which 

 is consequently more or less uneven ; they are very fine and thread-like, and, being 

 crossed by the transverse striae, are cut up into elongate sections. The peripheral dark 

 line is very indistinct and may be an individual peculiarity. 



10. HoMOEus BicoLOR, sp. n. (Plate I. fig. 15.) 



Testa mediocriter elongata, nigro-rufescens, ad apicem flavescens, nitens, lineis 

 incrementi obliquis, striisque spiralibus tenuibus sculpta; spiraad apicem obtusa; 

 anfractus 6^, regulariter crescentes, valde convexi, superiores 2\ flavescentes, 

 ultimus perconvexus, striis spiralibus minus distinctis ; apertura inverse auri- 

 formis, intus purpurascens, longitudinis totius f adsequans ; labrum extra 

 incrassatum ; columella in medio arcuata, antice oblique truncata. 

 Longit. 16 mm., diam. Q\; apertura 6 mm. longa, 3^ lata. 

 a. Mubuku Valley, E. Ruwenzori, 7000 feet. 



This species is remarkable on account of the yellowish apex, which contrasts 

 strikingly with the rest of the shell, and for the thickening of the labrum on the 

 outside with a rounded rib, a feature which perhaps may prove to be of generic 

 importance.
