388 Dr. Strahl on new Thalassine from the Philippines. 
it impossible to decide whether this inner point is moveable. It 
is probable that the inner point is moveable, but the outer one 
is not; consequently the outer point belongs to the armiger, 
but the inner may be the true scale. Both points, however, are 
of equal length; the inner one retains the same width for about 
two-thirds of its length, then narrows, gradually becoming round, 
and runs on in its last third into a fine point; the outer one, on 
the contrary, runs gradually and uniformly to a pot. The 
second antennal joint is the longest, and projects a little beyond 
the two points just mentioned. The outer maxillipeds are foot- 
like; close to them externally is a palpus with a long flagellum. 
The branchi are in tufts, but the fifth pair of feet bears no 
branchie. 
Of the two pairs of cheiz the first is the strongest, and the 
two legs are of equal length and strength. The hands are late- 
rally compressed, with the upper and lower margins rounded off; 
the fingers are acute, half as long as the hand; the carpus is 
triangular, that is to say, the anterior and posterior (articular) 
margins meet below in an obtuse angle; the upper margin, or 
third side, however, is not straight, but convex superiorly. 
The second pair of chelz is of about the strength of the posterior 
ambulatory feet ; the hand, including the fingers, is of the same 
length as the carpus ; the latter is broader in front than behind. 
The fifth pair of feet is thinner than the third and fourth. The 
claw-joint is of the same strength as the rest. 
The abdomen, like all the rest of the body and its members, 
is quite smooth and naked; the tufts of hair on the sides of the 
abdominal segments, which distinguish Awius stirhynchus, are 
wanting. The lateral appendages of the abdominal segments 
are but short. The first segment is narrow; the segments gra- 
dually increase in length up to the sixth: the caudal scale, 
again, is smaller, broadly truncated behind; the lateral appen- 
dages belonging to it, especially the outer ones, are long. When 
these parts of the tail-fin are spread out like a fan, their outline 
is the same as that of the caudal scale. The abdominal appen- 
dages on the first segment are simple; the following ones con- 
sist of a basal joint, from which two broad, feathered, pointed 
laminz, equal in length and breadth, are suspended; the inner 
one has also a stalk-like process on its inner margin. 
Gebia barbata, n. sp. 
This new species is likewise a native of Luzon. Sexually 
mature examples are about 1 Paris inch in length. 
The forehead is perpendicularly truncated m front, asim G. 
major, De Haan, so that it does not terminate in a point, as in 
G. littoralis, Risso; it is densely clothed with short hairs, and
