of the Fishery Board for Scotland. 269 
species of Typhlotanais has been observed in the British seas, and that 
this should be so is the more interesting from the fact that no fewer than 
nine species are known to occur off the coast of Norway, but the majority 
of them are small, and limited in their distribution to moderately deep 
water, and this may account to some extent for their having escaped notice 
hitherto. The length of Typhlotanais brevicornis is only about 13 mm. 
Paratanais batet, G. O. Sars. 
This species was collected by the “‘ Garland” in Loch Etive in 9 fathoms, 
off A.bbot’s Island, on March 30th. This is a new station for Paratanais 
batec on the West Coast. 
Leptognathia breviremis (Lilljeborg). 
This was collected by the ‘‘ Garland” off Aberdeen in 45 fathoms on 
November 11th last year. 
Leptognathia brevimana (Lilljeborg). 
L. brevimana is a more slender species than the last, and is readily 
distinguished by the structure of the uropods, the outer branches of 
which appear to be but spiniform prolongations of the outer angles of the 
basal joints. I have one or two records of this species for the Moray 
Firth, where it has been taken by the “ Garland,” as well as off Aberdeen, 
where it was collected in 45 fathoms along with the next form on 
November 11th. 
Leptognathia (?) longiremis (Lillj.), var. (Pl. XVIIL, figs. 30-38.) 
In the female of this Leptognathia the body is elongated and narrow, 
being about seven times longer than broad (fig. 30). The terminal segment 
of the metasome has no apparent denticle on its lateral margins as in 
Leptognathia longiremis (Lilleborg). The antennules (superior antenne) 
are moderately elongate, being equal to about one-seventh of the length of 
the body ; in the majority of the specimens examined the antennules were, 
four-jointed (fig. 32), but, on the other hand, a number were observed 
which had the antennules distinctly five-jointed (fig. 33), though in other 
respects they appeared to be identical with those possessing the four- 
jointed antennules. In the four-jointed antennules the first joint is 
scarcely so long as the combired lengths of the next three joints, the 
second and the last joints are nearly equal, while the third is only equal 
to about half the length of the preceding joint. Im the five-jointed 
antennules the first joint is about twice es long as the second; the 
second, in its turn, is about the length of the third joint ; the fourth joint 
is very small, while the end-joint is nearly as long as the entire length 
of the third and fourth. 
The antennz (inferior antenne) are very similar to those of Lepto- 
gnathia longiremis (Lillejborg), (fig. 35). 
The chelipeds (fig. 36) and the walking legs are very similar to the 
same appendages in the female Leptognathia longiremis. 
The inner branches of the uropods, which are elongated, consist of two 
sub-equal joints, but the outer branches, which are also two-jointed, are 
scarcely as long as the first joint of the inner branches (fig. 38). Length 
of the female scarcely 2°5 mm. 
In the male the body is considerably shorter and broader than that of 
the female (fig. 31). The antennules are proportionally longer than those 
of the female ; the first two joints of the peduncle are dilated, but the
