Chloeia ; but the attachment of the oblique muscles at the sides, and the relation to 
the other parts are the same. The circular muscular coat of the intestine is also 
strongly developed. It is noteworthy that this and the previous kinds so often have 
empty intestinal tracts. As in many fishes, the digestive process is probably rajDid. In 
vertical longitudinal section the posterior part of the great muscular cushion or tongue 
presents an easily separable series of the usual vertical muscular lamellse, transversely 
arranged. They possess a somewhat fan-shaped appearance. 
This form cbfiers from Grube’s Notopygos crinitus in regard to the branchiae and the 
structure of the bristles as shown by Kinberg.^ There is considerable doubt in regard to 
its connection with Notopygos macidata, Kinberg,^ from the island of Panama, which 
Semper also found at Bohol in the Philippines;^ but in the characters above-mentioned it 
also deviates from this species. A re-examination of the bristles of Notopygos maculata 
would help to remove ambiguity.

Habitat. — Several fine examples were procured at the surface of the sea near the 
Bermudas, some being captured along with a large Hermodice on a log. Amphinome 
vagans is occasionally found under the same circumstances on floating timber. 
All the specimens are distinguishable by very evident external characters in spirit, viz., 
the peculiar slate-blue of the entire body, and the ferruginous hue of the tentacles, cirri, 
and branchiae. The smaller specimens have the bluish colour of the body less marked, 
especially ventrally. A small example of Amphinome vagans, Leach (Sav.), procured 
from the Godefiroy Collection, and named by Grube, shows this colour on the dorsum, 
while the ventral surface is pale buff ; and the latter colour characterises another all over. 
Since the description by Pallas, no author has entered minutely into the characters of 
the animal, and therefore it is necessary to do so on the present occasion, as at least one 
species [Amphinome vagans) is closely allied. 
The body is elongated and somewhat tetragonal, the following numbers of body-seg- 
ments occurring respectively in the examples : — 56, 56, 50 (imperfect), 52 (imperfect), 46 
(small), 48 (imperfect), 50 (imperfect), 49, 51, 54, 52, 58, 59, 57, 51. Pallas gives 66 as 
the total number in his small specimen, 55 in the larger. Segments are so readily throvm
