THE VOYAGE OF H.M.S. CHALLENGER. 
Station 156. Am PH IPOD A (Stebbing, Zool. pt. 67). 
Valettia coheres, n.g., n.sp. One specimen ; obtained at no other locality. Only 
species of the genus. 
Isopoda (Beddard, Zool. pt. 33). 
St-ro/is bromleyana, Willemoes-Suhm, n.sp. Two specimens ; obtained also at 
Stations 164, 168, and 169, 400 to 1100 fathoms. 
Macrura (Spence Bate, Zool. pt. 52). 
Ilymenodora rnollicutis , n.sp. One specimen ; obtained also at Stations 87, 104, 
133, 157, and 318. 
Polyzoa (Busk, Zool. pt. 30). 
Bicellaria in/undihulata, n.sp. Obtained also at Station 147. 
Fishes (Gunther, Zool. pt. 57). 
Melanonus gracilis, n.g., n.sp. One specimen ; obtained at no other locality. Only 
species of the genus. 
Gonostoma microdon, n.sp. One specimen ; for distribution see Station 23. 
Scopelus antarcticus, n.sp. One specimen; obtained also at Station 157, 
1950 fathoms. 
The fishes were alive when brought up. All the scales of Melanonus were off except 
two, which had a brilliant metallic reflection. 
In addition to the foregoing, Palythoa , Actinian, and egg-capsule are recorded in the 
Station -book. 
Excluding Protozoa, about 100 specimens of invertebrates and fishes were 
obtained at this Station, belonging to about 37 species, of which 32 are new to science, 
including representatives of 13 new genera ; 13 of the new species and 6 new genera 
were not obtained elsewhere. 
Willemoea-Suhm writes : “ The bases of the arras in the Brisinga [ = FreyeUa 
frayUi*'inui \ "were occupied by an ovary, in which the eggs attained a considerable size, 
nearly equal to those in the pouches of the Kerguelen Schizaster. In many groups of 
the lower animals it is possible to tell, from the size of the egg and the smaller or greater 
quantity of yelk to be disposed of by the future embryo, whether there is a metamorphosis 
or a direct development ; the latter is very likely the case here. In the Gephyrean no 
prolioecis nor anus was seen ; the twisted intestine was as in Sipunculus, and was filled 
with mud shining through the skiu. It lived in a mud tube. The worm-tubes, belonging 
to a Nephthys-Uke Annelid, were remarkable for the large Foraminifera used in their
