(Plate XXV.) 
Pleurotoma (Mangelia) Brionh:, sp. nov. (PI. XXY. 
figs. 14, 15.) 
Testa elongata, anguste turrita, pallide fulva, transversim obscurissime 
fusco multi-lineata ; anfractus 9, convex!, spiraliter minutissime densissitne 
striati, longitudinaliter costati, sutura impressa sejuncti ; anfractus ultimus 
parviusculus, leviter convexus, costis 10 elevatis lsevigatis 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. ; apert. long. 7i> maj. lat. 2\ millim. 
Hab. Hongkong. 
This species somewhat resembles an elongated form of the 
British P. nebula , hut 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. Huugerford from Hongkong. 
Oliva BGlowi, sp. nov. (PI. XXY. fig. 3.) 
Testa subcylindraceo-fusiformis, lutea, obscure griseo nebulata, antice 
conspicue rufo-fusco flammata; spira acuminata; anfractus 7; planato 
declives, griseo-fusco obscure fasciati, sutura canaliculata sejuncti ; anfractus 
ultimus supra medium obscure angulatus, infra medium flam mis 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. 
Hab. 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 Biilow 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. nov. (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 
longitudinaliter costellati, spiraliter multisulcati, deinde spiraliter striati, 
haud costellati ; anfractus ultimus spiram subsequans, rotunde con-
