340 ADDITIONS AND CORRECTIONS. 



Add the following Marianne and N atuna Island species of Charopa r 

 Nachr. D. M. Ges. 1894, p. 13, 14 : 

 E. fusca Quadr. & Mlldff. E. quadrasi Mlldff. 



E.rotula Quadr. & Mlldff. E. persculpta Sm., Ann. Mag. '94. 



The Helix (Helicella) australis of Menke, from Mt. Eliza, Swan 

 River, may possibly belong to Charopa if it is really Australian 

 but it certainly does not look like one. See vol. iii, p. 103. 



On p. 33, E. microscopica Cox (not Krauss) must be dropped in 

 favor of E. microcosmos Cox. 



On p. 34, E. " cupera " Coxcuprea. For " retepora " and " re- 

 teporoides," read reiipora and retiporoides. 



Genus PHASIS Alb., and Trachycystis Pils. (p. 37). 



Suter (Ann. Mag. N. H. 1894, p. 60) believes a caudal pore to 

 be present in Pella burnupi, the dentition of which he figures. None 

 was visible in the badly preserved specimens of P. rariplicala ex- 

 amined by me. On p. 39 the following corrections should be made : 



P. inclara Morel. P. zanguebarica Crav., iii, 105. 



H. inops Morel, not Mouss. 



Genus SCULPTARIA (p. 39). 



Possibly this may prove to be a genus of Protogona. Ponsonby 

 writes that Ancey's S. chapmanni (subsequently changed to S. mel- 

 mlliana, Brit. Nat. 1892, p. 126) has been compared with the type 

 of damarensis H. Ad., and found to be absolutely the same. 



Genus AMPHIDOXA (p. 41). 



A. chiliensis Muhl. (not chilensis). 

 A. tenuistria Phil, (not tenuistriata). 



Genus PYRAMIDULA (p. 42). 

 Section Microconus Strebel & Pfeffer, 1880. 



Microconus STREBEL & PFEFFER, Beitr. Mex. Land- und Siiss- 

 wasser-Conchyl. iv, p. 29, type M. wilhelmi Pfr. 



This name is proposed for a small species of eastern Mexico resem- 

 bling Pyramidula rupestris in contour, but ribbed as in P. rotundata 

 or perspective It can hardly be regarded as more than a "section '* 

 of Pyramidula. The position of hermanni taidmazatlanica isdoubt- 

 ful. '
