9. PsEUDOGLESSULA LeKOYI, Bourg., VUI'. OBTUSA, ll.Vai'. 



PI. XVII, Fig. 2. 



DifFert a typo spira obtusa. Long. 32, diani. 15-5 mm.; apeitura, 

 alt. 13, lat. 8*5 mm. 



Hab. — Pugu, 19 km. from Daressalam, German East Africa. 



This new variety is less elongated than the typical form of the 

 species, but shows in all other respects a close relationship. I received 

 this form from Mr. G. Naegele. 



10. PsEUDOGLESsuLA Naegelei, n.sp. PL XVI, Fig. 5. 



Testa perforata, elongata, anguste stiiata, nitens, non solida, 

 cornea. Anfractus 8, convexiusciili, sutura subimpressa separati ; 

 ultimus \ longitudinis paulo minor; apertura ovata; peristoma 

 tenue, retlexum ; margo columellaris reflexus, cum basali angulum 

 indistinctissimum formans ; margines callo tenue juncti. Long. 17'5, 

 diam. 7'5mni.; apertura, alt. 6, lat. 4 mm. 



Hah. — Kipatimu, German East Africa. 



Shell perforate, elongate, finely striate, shining, not heavy, 

 corneous ; whorls 8, somewhat convex, separated by a not very 

 impressed suture, the last measuring less than one-third of the lenpth 

 of the shell ; aperture ovate ; peristome thin, reflexed ; the margin 

 of the columella reflexed and forming a very indistinct angle with 

 the basal margin ; the margins united by a thin callus. 



This species is allied to P&eudoglesuda introve^'sa, E. A. Smith, but 

 is easily separable, being more slender and somewhat larger. The 

 perforation in P. Naegelei is also larger, and the shell is corneous, not 

 greenish corneous as in P. mtroversa. The whorls also increase more 

 gradually, and the aperture is smaller. For comparison, a specimen 

 of P. introversa from the same locality is figured (PI. XVI, Fig. 6). 

 I have the pleasure to connect with the new species the name of 

 Mr. G. Naegele, from whom I received it. 



11. Rhachis Staulbergi, n.sp. PL XVII, Fig. 3. 



Testa rimata, elongata, conica, subcarinata, anfractibus superioribus 

 rubris, inferioribus albescentibus, supra carinam striis carneis longitudi- 

 nalibus, sub carinam deticientibus ornata ; carina linea nigrescenti- 

 fusca comittata, supra quam anfractus mediani guttis ejusdem coloris 

 ornati ; anfractus 7, superiores subconvexi, sequentes plani, regulariter 

 accrescentes, sutura planissima separati ; ultimus circa f longitudinis 

 totius oequans. Apertura oblongo-ovata, obliqua, linea externa trans- 

 lucente; peristoma simplex, acutum ; margo columellaris albescens, 

 cum basali angulum indistinctum formans. Long. 14, diam. 7 mm. ; 

 apertura, alt. G'5, lat. 4 ram. 



I£ab. — Atakpame, Central Togo. 



Shell rimate, elongated, regularly conical, slightly carinated, upper 

 whorls red, elsewhere whitish, above the carina ornamented with fine 

 flesh-coloured longitudinal stripes, which are wanting below the 

 carina ; carina provided with a dark blackish-brown band, which on 

 the middle whorls is bordered above with dots of tbe same colour; 

 whorls 7, upper whorls moderately convex, the others flat, regularly
