of carbonate of lime (Station 93 g). At 6.35 p.m. stopped and sounded in 1150 fathoms, 
deposit Volcanic Mud, containing 4752 per cent, of carbonate of lime (Station 94). At 
7.25 p.m. made all plain sail, and proceeded towards Porto Praya, St. Iago. 
Surface Organisms. — Willemoes-Suhm writes : “At night a great many small speci- 
mens of Pyrosoma were in the water, and some were taken in the tow-net. Also, an 
Acridium came on board.” 
The Challenger remained at St. Iago from 7.30 a.m. on August 7 till 8.30 p.m. on 
August 9, during which time the steam pinnq.ce dredged and trawled with tangles on 
the Red Coral ground, in 80 to 100 fathoms. 
The expedition visited the Cape Verde Islands on the outw T ard voyage from Juty 27 
till August 9, 1873, and on the homeward voyage from April 16 till April 26, 1876 
(for description of the islands, see Narr. Chall. Exp., vol. i. pp. 183-191). On both 
visits, Air. Murray conducted dredgings from the steam pinnace in the harbour of St. 
Vincent in depths of 7 to 50 fathoms. The deposit was a Calcareous Sand, containing 
87 to 94 per cent, of carbonate of lime, chiefly made up of Foraminifera and Calcareous 
Algae. In some places the shells of Aviphistegina lessonii made up fully two-thirds of 
the whole deposit. Polystomclla, Discorbina, and Orbiculina were also abundant. 
The deposits around the islands from 200 fathoms down to 1150 fathoms w r ere Volcanic 
Sands and Muds, containing from 13 to 50 per cent, of carbonate of lime, in which 
Pteropod and Heteropod shells were abundant. The following species are recorded in 
the Zoological Reports as having been obtained in the vicinity : — 
Monaxonida (Ridley and Dendy, Zool. pt. 59).

other locality.

water) ; obtained at no other locality by the Challenger. 
Recorded from British Islands and Port Jackson.

Harbour, 7 to 20 fathoms) ; obtained at no other locality.
