KALIELLA FILOCINCTA, Heude. PI. 63, figs. 3-5. 



Imperforate, pellucid, costulate above, brown ; whorls 6, the 

 last with a conspicuous thread-like carina. Diam. 7'5 mill. 



Tchenkeou, China. 

 KALIELLA CUNEUS, Hcude. PL 63, figs. 6-8. 



Narrowly umbilicated, fulvous, scabrously obliquely costulate 

 above, smooth below; whorls 7, slowly increasing, the last 

 carinate, suture impressed. I)iam. 7 mill. 



China. 

 XESTA VITELLUS, Shuttlew. (p. 60). 



Has been found varying in color as much as N. citrina, one 

 variety being evidently the Hemiplecta Clairvillia, Fer. (p. 35). 

 It should take the latter, being the oldest name. MARTENS, 

 Sitzb. Berlin, 113, 1886. 



XESTA SIBYLLA, Tapparone-Canefri. Celebes. 



The publication containing this and other species came to 

 hand too late to include them in their proper places. 



XESTINA ALBATA, Blandford (p. 83). 



This name being preoccupied by Fagot for a quaternary 

 fossil, Mr. Ancey changes it to X. lucublanda. He also removes 

 it to the Helicidse, in the neighborhood of the group Fruticicola. 



MACROCIILAMYS KREFFTI, Cox. PI. 63, figs. 98, 99. 



Perforate, thin, pellucid, smooth, very glossy, microscopi- 

 cally striated, brownish yellow ; whorls 5, the last with rounded 

 periphery, suture slightly margined. Diain. 12'5 mill. 



Cape York, and near Cape Flattery, Australia. 



On page 105 I follow Dr. Cox in considering his H. Kreffti a 

 synonym of mllaris, Pfr. The latter species, as figured by 

 Reeve, appears to differ specifically from Cox's figure. 



MICROCYSTIS ORBICULUM, Tapparone Canefri. N. Guinea. 



MICROCYSTIS BRUIJNII, Tapparone-Canefri. N. Guinea. 



SESSARA BOUYERI, Crosse and Fischer. PI. 63, fig. 90.
