Crustacea.—The Crustacea of the Norwegian North Atlantic 
Expeditions, excluding forms previously established as belonging 
‘to the Norwegian littoral fauna, have been described by G. O. 
Sars. They comprise: Brachyura, 1 sp.; Anomoura, 1; Caridea, 
4; Myside, 5; Cumacee, 1; Isopoda, 18; Amphipoda, 45; a 
copepod, Eucheta norvegica, always found at considerable’ depths, 
six cirripeds and Stylon hymenodore, a rhizocephalon attached 
parasitically to the abdomen of Hymenadora glacialis, and dredged 
i oms. Bythocaris leucopis and payert, true deep-sea 
carideans of the North Atlantic (1110 fathoms), do not pass 
through. the usual larval stages, but on quitting, the remark- 
ably large embryos have the full number of appendages found in 
the parent. . Hymenodora glacialis has an exopodite attached to 
the outer side of the second joint of the legs, as in the schizopods. 
Boreomysis scyphops, a schizopod taken by the Norwegian 
North Atlantic expedition has very singular eyes. The outer

Sphyrapus serratus Sars, is a singular sightless isopod which 
occurs in the open sea between Norway and Iceland, at depths of 
from 1163 to 1333 fathoms. It has nineteen paired appendages. 
The first pair of legs springing from the posterior part of the 
cephalic segment, are powerful prehensile organs. The second 
pair of legs are as long as the body, flattened, and armed with 
powerful spines. Five pairs of slender walking feet follow, and 
are followed by five of biramous swimming feet and a pair of long

ON AN UNUSUAL RELATION OF THE NOTOCHORD TO THE INTES- 
TINE IN THE CHICK.—Through the great kindness of Dr. G. Baur, 
: the Peabody Museum, New Haven, Conn., I am enabled to 
gure an apparently rare mode of development of the notochord 
- in the embryo chick. In order to enable the reader to more 
readily understand the peculiar morphological relations to each 
other of the posterior ends of the nervous cord, chorda and intes- 
tine in the series of sections prepared by Dr. Baur, 
endeavored to tombine in one figure what seemed to me to be a 
_ correct interpretation of the relations of the parts involved.
