NARRATIVE OF THE CRUISE.

more delicately than I could do. In any case this unique treasure is not lost. 
From the same neighbourhood there were some very beautiful Trochuses of the Mar- 
garita group, such as Trochus ( Margarita ) brychius from 1260 fathoms, far to 
the southeast of Kerguelen. Full-grown shells of Valuta ( Volutilithes ) abyssicola, H. 
and A. Ad., a species that has long been an object of interest from its connection with 
Eocene forms, but which was hitherto known only in one very young specimen, have been 
brought from near the Cape of Good Hope. Turbo transenna, a remarkable new 
form, comes from 565 fathoms near Japan. Gaza clcedala, a new and very beautiful 
Troclius, was got in 610 fathoms off Fiji. The great group of the Pleurotomas is 
largely represented in species, and coming, as many do, from very deep water, they are of 
great interest, but in the main the specimens are few and poor. 
“The presence of the fossil genus Acteonina, though in its least characteristic form, 
and distinguishable indeed from Actceon only by the absence of pillar teeth, is not with- 
out interest. Two of the Scaphanders, Scaphander mundus and Scaphander niveus, 
from the neighbourhood of the Philippines in 800 and 500 fathoms respectively, are 
very fine. 
“ That no addition either of species or of specimens should have accrued to the very 
limited number of living Pleurotomarias — distinctively a deep-water and very ancient 
genus — is a disappointment. 
“ As regards distribution, the habitat, hitherto unknown, of some littoral species has 
been determined. One or two almost forgotten species, such as Trochus (. Diloma ) 
porciter, A. Ad., have been recovered in their own home ; but what is probably of highest 
interest is the proof obtained, though hardly for the first time, (1) of the existence of 
species such as Puncturdla noachina, Linn., Dentalium entails, Linn., Scissurella 
crispata, Flem., and Hornalogyra atomus, Phil, in both Arctic and Antarctic waters; 
and (2) of the wide extension in the ocean of still surviving fossil species such as 
Dentalium dentalis, Linn., Puncturdla noachina, Puncturdla ( Cranopsis ) granulata, 
Seg., and Puncturdla ( Fissurisepta ) rostrata, Seg., Italian Miocene fossils with others 
from the Pliocene. 
“ In a general way the facies of the deep-sea Molluscan fauna may be said to be pale- 
ness and fragility. If the number of new species and genera is larger proportionally in 
the deep than in the shallow water Stations, the fact can only be taken as indicating that 
a hitherto unexplored field has been entered on.” 
The Anornura. — Mr. J. P. Henderson, M.B., C.M., who has undertaken the prepara- 
tion of a Report on those families of Crustacea frequently grouped under this name, 
writes: — “The Challenger collection of Anornura has only recently been placed in my 
hands, and I have not yet had time to make a detailed examination of all the 
specimens. The collection, which is an extensive one, contains many new forms of
