Searle (1911) has followed Smith (1909) who has apparently confused the 
right and left fifth legs in the male. The long, curved, terminal claw is on the 
right leg, as shown by Henry (1924). 
BRUNELLA SALINA sp. nov. 
Occurrence. VI. Many specimens of both sexes. Of the 100 specimens exa- 
mined, representing about one-quarter of the total in the collection, 58 were fe- 
males and 42 males. Some of the females had spermatophores attached but none 
was found carrying eggs; it is very probable that, as with most of the other mem- 
bers of this family, the eggs are liberated directly into the water. In this respect 
Gladioferens would appear to be an exception. 
Female. Length 0:82-0:95 mm. The last thoracic segment is expanded into 
pointed, wing-like processes which are equally developed on both sides. That on 
the left, however, is somewhat more downturned than that on the right, giving an 
appearance of asymmetry. The urosome is 3-segmented, the genital segment hav- 
ing a prominent ventral protuberance; the caudal rami are a little more than 
twice as long as wide and about as long as the two preceding segments together. 
The first antenna is 25-segmented and reaches to the posterior end of the thorax. 
The remaining head appendages agree well with Sars’ description of longicornis 
except for the mandible palp of which the exopod is relatively longer than in 
Searle’s species, reaching slightly beyond the end of the elongate basis, and is ap- 
parently 4-segmented bearing 6 setae. The armature of the swimming legs appears 
to be subject to variation; the formula given below indicates what appears to be 
the normal condition, alike in both sexes : 
endopod. exopod. 
p-l. 320, 1.1.321. 
p-2. 2.421. 1,1.421. 
p.3. 2.421. 1.1.421. 
p.4. 2,321, 1.1.421. 
The following variations were found: the endopod of one of the first legs in 
a male had only two inner setae; the exopods of both first legs in a female had 
only two inner setae on the end segment; the endopod of one of the second legs 
in a female had only one inner seta on the basal segment; and the exopods of both 
third legs in a male had only three inner setae on the end segment. 
In the armature of the swimming legs considerable differences are shown from 
the deseription of longicornis given by Sars. In view of the variation found in 
salina however, this may be unimportant. 
The fifth legs have a 3-segmented exopod and 1-segmented endopod. The 
exopod is unarmed except for the inner spur or claw on the second segment, and 
two unequal spines on the end segment. The endopod shows small constrictions 
at the point of fusion of the segments, and is unarmed except for two small sub- 
equal terminal spines.
