De 2 forreste Par Halefpdder liar den ydre Gren be- 
)ielig kortere end den indre. Sidste Par, som ikke over- 
disse, bar derimod begge Grene ligeligt undyiklede 
(se Fig. 3 Jc). 
Halevedlneriget (ibid.) er forholdsvis af en ganske ual- 
®indelig Stgrrelse og rsekker nsesten til Enden af sidste 
ai Halefodder. Det er pladeformigt og af forkcnget tri- 
an gulaer Form, mod Sidekanterne glatte og Spidsen forsyuet 
>ned 4 smaa Tender. Ved en meget smal Fissur er det 
0vet indtil foran Midten. 
Farven er ensforinig gulgraa og kun lidet gjennem- 
sigtig. 
Liengden af det storste underspgte Exemplar er 8 1 / 2 ’”“. 
The 2 anterior pairs of caudal stylets have the outer 
branch considerably shorter than the inner. The last pair, 
which do not reach beyond them, have, on the other hand, 
both branches equally developed (see fig. 3 k). 
The telson (ibid.) is comparatively of quite a remarkable 
size, reaching almost to the extremity of the last pair oi 
caudal stylets. It is lamelliform and elongate-triangular, 
with the lateral margins smooth and the point furnished 
with 4 small teeth. An exceedingly narrow fissure cleaves 
it till past the middle. 
Colour a uniform yellowish -grey, and but slightly 
translucent. 
Length of the largest specimen examined 8 1 / 2 mm .

Occurrence and Distribution. — A few individuals of 
this very distinct species were obtained, on the 2nd cruise 
of the Expedition, in the sea west of the coast of Helge- 
land (Stat. 124), from a depth of 350 fathoms. This Sta- 
tion belonged to the cold area. The same species I have 
also taken in the Korsfjord, south of Bergen, and at Lof- 
oten, where a third and new species of the same genus, 
B. tuberculata. is found to occur.

Specific Character. — Body less thickset than usual, 
somewhat compressed. Lateral corners of head slightly 
projecting, and rounded. Fourth pair of epimera rounded 
triangular’ about as large as the 2 preceding pairs taken 
together. Eyes very small, round, with red pigment. An- 
tenna?, alike in female and male, most unequally developed ; 
2nd pair almost twice as long as, and much more powerful 
in structure than,. 1st, well-nigh pedifonn, with the 2 last 
joints of peduncle greatly elongated; flagellum exceedingly 
small and slender. First pair of legs feeble in structure, 
with 3rd joint jutting out below as a narrow, rounded lobe. 
Second pair of legs in both sexes powerfully developed, 
with hand exceedingly large and swollen, palmar margin 
oblique and irregular-sinuous, with a single small denti- 
form projection in the middle, and bounded below by a 
strong , acute apophysis, in the male deeply incurved
