THE VOYAGE OF H.M.S. CHALLENGER. 
Station* 174 
to 174d. 
were: Peridinium, orbular green Algae ( Halosphsera ?), Pyrocystis, Acanthometrae and 
other Radiolarians, Siphonophorze in all stages with eggs, larvae of Holothurians, 
larv.e of Aphroditaceans, Sag it to, Saphirina, Zoeae, Pteropods and larvae, Appcndicularia , 
S(d pa. On August 3 the tow-net was sent down to 20 fathoms, and produced many 
< Lrilhitorinceae, the spherical green Algae (Halosphasra), Pyrocystis, Globigenna, Orbulina, 
(no PulvinulinsB noticed), Sagitta, many Crustaceans, and Pteropods. In the stomachs 
of the Salpse were many minute organisms, both siliceous and calcareous, two forms of 
Rhabdospheres, one especially abundant, and many forms of Coccospheres. 
Two sharks (male and female) were caught, belonging to the same species 
(Cai charias lamia). About one of them were several specimens of Naucrates ductor ; 
there were many sharks about at the time, so that there appears to be no truth in the 
statement that Naucrates does not accompany sharks when there is more than one shark 
present. In the female the ovaria were double, and the oviduct soon dilated into a very 
large uterus on each side, each of which contained four young sharks about 2 feet in 
length, all attached by an umbilical cord to a placenta. 
At Fiji. 
The Challenger Expedition remained in the vicinity of the Fiji Islands from 
July 24 till August 11, 1874, visiting Matuku, Kandavu, and Ovalau (for description 
of the Islands see Narr. Chall. Exp., vol. i. pp. 487-509). The following species are
