42 A. E. Verrilli—Results of recent Dredging Expeditions 
ALG A. 
The following occurred in 124 fathoms: 
arum Turneri. Pisce Se mee Callithamnion, sp. 
Delesseria sinuosa. Euthor Corallina officinalis. 
D. alata. Ptilota phic erg Lithothamnion papper 
Farther to the west, off the mouth of Casco Bay, and abou 
two to three miles south of Half-way Rock, in 27 fathoms, we 
made — haul, very similar to t the one in 83 fathoms, de- 
scribed above. The bottom was here composed of coarse sand 
= grieved pebbles, small stones, and broken shells, with some 
A large proportion of the species given in the list for 
the 33-fathom locality also occurred at this place, with many 
additional ones, among which were the following: 
Crustacea. 
Eupagurus Bernhardus. acea, two sp. Ampelisca, sp. with red 
Crangon vulgaris. Ptilocheirus pinguis. dorsal spots. 
Hippolyte Fabricii. Anonyx, sp. Ampelisca, small sp. 
Anthura brachiata.

Cyclocardia Novangliz. | Yoldia sapotilla. 
Echinoderms. : 
Hippasteria phrygiana, one large specimen. _ 
In Casco Bay, among the islands, in moderately shallow 
water, there is great diversity in the character of the bottom, 
and a large amount of profitable dredging was done. Most of 
the peice are decidedly boreal and arctic forms, which we had 
pepe dredged in the Bay of Fundy, and farther north. 
he Pas varied from 8 or 4 to about 80 fathoms. Some of 
oe best localities on hard bottoms were found in Husse 
etc. In these Jooalities the bottom was com ‘of small 
stones, and occasionally of rough rocks with broken shells, 
gravel, ete., overgrown by an abundance of coarse massive 
sponges, among which were several species of Reniera, Halt- 
chondria, Suberites, Polymastia, etc., here with more delicate 
species belonging | to Chalina, Isodictya,
