 (Plate XXV.) 



Pleurotoma (MANaELiA) Brion^, sp. nov. (PI. XXV. 

 figs. 14, 15.) 



Testa elongata, anguste turrita, pallide fulva, transversim obscurissime 

 fusco multi-lineata ; anfractus 9, convexi, spiraliter minutissime densissime 

 striati, longitudinaliter costati, suturaimpressa sejuncti ; anfractus ultimus 

 parviusculus, leviter convexus, costis 10 elevatis Isevigatis munitus, ad 

 basin acuminatus^ vix productus; apertura oblonga, mediocriter lata, 

 utrinque angustior ; columella rectiuscula ; labrum arcuatum, postice paulo 

 sinuatum. 



Long. 20, maj. diam. 6 millim. j apert. long. 7h maj. lat. 2| millim. 

 Hah. Hongkong. 



This species somewliat resembles an elongated form of the 

 British P. nebula, but is considerably larger, and distinguishable 

 by a very long and turreted spire. The shell is apparently 

 smooth, and the very fine spiral striae can only be seen through a 

 lens. The longitudinal ribs are rounded and smooth. Only one 

 perfect specimen was brought by Dr. Hungerford from Hongkong. 



Oliva Bflowi, sp. nov. (PI. XXY. fig. 3.) 



Testa subcylindraceo-fusiformis, lutea, obscure griseo nebulata, antice 

 conspicue rufo-fusco flaramata; spira acuminata; anfractus 7, planato 

 declives, griseo-fusco obscure fasciati, sutura canaliculata sejuncti ; anfractus 

 ultimus supra medium obscure angulatus, infra medium flamrais rufo-fuscis 

 obliquis peculiariter pictus ; columella rectiuscula, 7-plicata, basi contorta, 

 albo callosa, unisulcata ; apertura modica, antice paulo latior, intus albida ; 

 labrum fere rectum, leviter complanatum. 



Long. 32, maj. diam. 13 millim. 



Hah. New Britain. 



This shell resembles 0. emicator (Meusch.) in form, but the 

 colouring is very peculiar and characteristic, with conspicuous 

 reddish-brown flames only on the lower part of the body-whorl. 

 The type specimen is in the collection of Mr. Carl Billow in 

 Berlin, and is the largest I have seen ; the smallest is about 

 20 millim., and the average length is about 26 millim. 



MiTRA eormosensis, sp. uov. (PI. XXY. figs. 4, 5.) 



Testa fusiformis, fusca, albo-fasciata ; spira elongata, acuta ; anfractus 1 1, 

 leviter convexi, sutura impressa sejuncti, albo unifasciati, primi 8-9 

 iongitudinaliter costellati, spiraliter multisulcati, deinde spiraliter striati, 

 baud costellati ; anfractus ultimus spiram subsequans, rotunde con-
