THE VOYAGE OF H.M.S. CHALLENGEK. 
Station 229. Seiyestes, crab, ZoeJB, Idalobates, lanthina, small shells, Glaucus, Atlanta, Cardiojpoda, 
Carinaria, Pneumonoderma, Euryhia [ = Halopsyche~\, Hyalaea [ = Cavolinia'], Styliola, 
Cleodora [ = CUo^ halantium, Appendicidaria, Salpa, Pyrosoma, several fishes (large 
Stomiaticlm and Scopelids four inches in length). A shark was caught, a female 
Carcharias, six feet in length, with the tips of the fins white. 
Wdlemoes-Suhin writes : “ The tow-net brought in some very fine things. Salpse 
and Medusm filled the water, along with very large Collosphmridse. There were also 
Ctenophorm, huge specimens of Alciopa with intense black spots, small Tomopteris, 
Crustacea in great abundance, especially Copepods, and Amphipods belonging to the 
genera Anchylomera and Hyperia, and also Dithyrus, the coxae of the pereiopods of 
which are so singularly enlarged as to form a ventral cavity with the abdomen, and closes 
up the animal entirely. Phyllosoma was very common in all stages, and will furnish 
very valuable material for working out the development of the Pacific Loricata. The 
specimens of Ilalobates were constantly smaller than the Atlantic specimens. There 
were many small fishes, including Stomiatidse with phosphorescent lateral spots, some 
over two inches in length. Velella, which has seldom been taken, made its appearance, 
along with its parasite lanthina, and Porpita and Glaucus. Among the Pteropods I 
found several specimens of Cleodora halantium with the animals — a Mollusc we have 
never taken alive before, and is, I believe, considered to be very rare.”
