was added, unless I may except a lot of Ophiocreas attached to a Prim- 
noa, and a pretty species of Sigsbeia attached to a species of Allopora, 
from the south side of Chatham Island. 4 
The Gorgonians were remarkably few in number. This is undoubt- 
edly due to the unfavorable nature of the bottom we worked upon. 
From the nature of the bottom we naturally expected rich hauls of 
Siliceons Sponges, but we did not find many, and I do not think there 
are many novelties among those we have collected. On two occasions, 
a number of specimens of Ascidians were brought up; among them was 
a fine white translucent Corinascidia. 
Among the Bryozoans, the most noteworthy haul was a number of 
beautiful specimens of the delicate Naresia (Kinetoskias), in excellent 
condition. On the line from the Galapagos to Acapulco we brought 
up a good many Foraminifera from the mud bottoms. On several occa- 
sions the bottom must have been covered with huge masses of a new 
type of an arenaceous Foraminifer, forming immense curling sheets at- 
tached by one edge to stones or sunk into the mud. This Foraminifer 
seems to increase in size by forming irregular more or less concentric 
crescent-shaped rings. When it comes to the surface, it is of a dark 
olive-green color. This and a species of Rhabdamina allied to R. lineata 
were the most striking Foraminifera collected. 
Among the Worms, the Maldaniz, Halinscia, Terebella, and limico- 
lous types were unusually abundant at some localities, the empty mud 
tubes often filling the bottom of the trawl. Some very large specimens 
of Trophonia were collected, and remarkably brilliantly colored (orange 
and carmine) Nemerteans and Planarians. 
The Mollusks were comparatively few in number, and the types emi- 
nently Caribbean. The absence of Comatul or other Crinoids was 
equally disappointing, even when trawling on the extension of the line 
started three years ago by the “ Albatross,” on the eastern face of the 
Galapagos slope, when on her way from Chatham Island to San Fran- 
cisco, although we were fortunate enough to bring up off Mariato Point 
in 782 fathoms a single fine specimen of Calamocrinus, with a part of 
the stem and its base, showing the mode of attachment of this genus 
to be similar to that of the fossil Apiocrinide. 
Two of the hauls made in the Gulf of California are specially worthy 
of mention, as being characteristic of the deep-water fauna of the Gulf of 
California, one made in 995 fathoms and the other in 1,588 fathoms. 
We obtained in these hauls a number of Ophiomusium and Ophiocreas, 
some fine specimens of Schizaster, a new genus allied to Paleopneustes,
