NOTES FROM THE “CHALLENGER” 
Vil. ‘ 
ON Monday the 30th of June we sounded in 1,000 fa- 
thoms, about 114 miles westward from Fayal. The 
dredge was put over early in the forenoon, and came up 
half filled with a grey sandy ooze with a large proportion 
of the dead shells of Pteropods, many Foraminifera, and 
many pebbles of pumice. Many animal forms of great 
interest were found entangled in the swabs, or sifted out 
of the mud, Another Schizopod crustacean of large size 
and great beauty of form and brilliancy of colouring 
came up in this,haul. Dr. von Willemoes-Suhm regards 
it as congenericjwith the species taken at Station 69, at a

depth of 2,200 fathoms, and as these crustaceans are 
among our most interesting acquisitions during the voyage 
between Bermudas and the Acores, I will abstract a brief 
description of them from his notes.

Lophogaster, a genus described in great detail by the late 
Prof. Sars. It is proposed to refer Guathophansia to the 
family Lophogastridz, which must be somewhat modified 
and expanded for its reception. 
In Guathophansia the dorsal shield covers the thoracic 
segments of the body, but it is unconnected with the last 
. Thomson—six times the natural size. 
Willemoes-Suhm proposes to establish the gene Gnatho- 
Phansia present characters which have hitherto been 
found partly in Schizopods and partly in Phyllopods, but 
not combined in the same animal. They are, however, 
essentially Schizopods, and have much in common with

five of these, The shield is prolonged anteriorly into & 
spiny rostrum. The stalked eyes are fairly developed in 
the ordinary position. There is an auxiliary eye on each 
of the maxillze of the second pair, : 
The two species of the genus are thus distinguished ;
