the ‘same dredge with this crustacean was found a fish of the 
group of Stomias, with lateral phosphorescent plates. Further 
on, at 1500 meters, several mollusks of unknown species (Scaph- 
ander, Pleurotoma, and Oocorys), the Dentalium ergasticum, a 
great variety of Crustacea, Holothurians, Asterians, Ophiurans 
and other Echinoderms, contrasted with the penury of the 
preceding days. 
After visiting Fayal, the Talisman explored the uneven vol- 
canic bottoms of the passages between the Azore islands, making 
several successful hauls at the depth of 1250 meters. Some 
fishes, large red Aristes, Heterocarpus, Galateas of the genus 
Diptychus, a squid (Cirrhoteuthis) peculiar to Greenland, Actinias, 
whose edges close together like a bivalve, many star-fishes, speci- 
mens of Lophohelia, with their usual retinue of Mopsea, soft sea- 
urchins (Calveria), large and beautifut Holtenias, recalling the 
redgings some weeks previously off the coast of Morocco. 
At a little distance from St. Michel, the declivity of the sea- 
bottom is very rapid. Some hours after our departure, our 
sounding apparatus already indicated almost 3000 meters, and 
some of the species found on the plateau situated west of Cape 
Ghir were brought up. Among others, some large Holothurians, 
of an amethystine color. On the following day the depth was 
4415 meters, and tor four days after it continued to be about the 
same. 4060 meters the 24th, 4165 the 25th, 4255 the 26th. 
The very large fishes of the genus Macrurus, which had been 
brought up during the expedition, also occurred here. They 
differed fromt hose of lesser depths. The Scopeli and Melanoceti 
were here also associated. Some hermit crabs and Galatheas of 
new form; some Crangons, with red eyes; a gigantic Nymphon 
of the genus Colossendeis; some Ethusas, different from those 
already known ; some Amphipods and Cirripedes represented the 
Crustacea. 
But this abyssal fauna owed its special physiognomy to the 
large Holothurians of strange forms which abounded; some 
whose length reached 0.65 millimeters, and whose violet colors 
were very intense, belonged to a new species of the genus Psy- 
chropotes, so remarkable from the existence of a very much 
developed appendage, ending behind the body, and resembling a 
queue; others, of the genus Oneirophanta, were easily recog- ; 
nized by their pure white color and long appendages, which 
garnished the whole body. Others of a delicate rose, carried on 
the back an erectile, fan-like membrane; these new Pentagonias 
were like those found by the Challenger at the greatest depths ex- 
plored. Finally, large Actinians, some of which lived as parasites 
on the Holothurians, some Hymenasters, Asterians, a Brisinga 
with few arms, some Ophiurans and a crinoid, were found in the 
same situations. 
Aug. 27th, the sounding apparatus reached a depth of over
