270 Part IIT.—Nineteenth Annual Report 
second is only about half as long as the first one ; the penultimate joint 
of the flagellum is distinctly louger than either the preceding or the 
following joints (fig. 34). 
The chelipeds of the male (fig. 37) are nearly as robust as those of the 
female; they are each provided with a transverse row of slender spines 
similar to those on the hands of-the male chelipeds in Leptognathia 
longirens. 
Habitat.—In the deep water off Aberdeen and in the Moray Firth ; not 
very rare. 
Remarks —This Leptognathia is, in its general appearance, as well as 
in some of its structural details, not unlike Leptoynathia longiremis 
(Lilljeborg), but it appears to be a smaller form, and it differs in the 
terminal segment of the metasome, having no apparent denticles on its 
lateral margins. 
In the male there are one or two marked differences, and especially in 
the structure of the antennules. In the antennules of the male of 
Leptognathia longiremis the last two joints of the flagellum are about 
equal to each other in length, and each of them is much longer than either 
of the two preceding joints, whereas in the form under consideration 
the end-joint is not much more than half the length of the penultimate | 
one, and its length does not greatly exceed that of the antepenultimate 
joint. Moreover, the inner branches of the uropods appear to be only 
two-jointed, whereas in the male of Leptognathia longiremis they appear 
from the drawings of Prof. G. O. Sars to be three-jointed.* Male 
specimens appear to be very scarce. 
Tanaopsis laticaudata, G. O. Sars. 
This tsopod, which I have recorded from the Clyde and one or two 
other places, has had its known distribution still further extended during 
the past year, having been obtained by the ‘‘ Garland” in Loch Etive, and 
also in Loch Eil (off the head of Loch Linnhe). The species was collected 
in Loch Etive near Abbot’s Island in 9 fathoms on March 30th, and in 
Loch Eil in 30 fathoms on April 3rd, 1900. 
Pseudotanais forcipatus (Lilljeborg). 
This species occurred along with the Typhlotanais brevicornis pre- 
viously recorded in the gathering collected in 50 to 55 fathoms, north-east 
of Buckie, on November 3rd. Pseudotanais forcipatus is not very rare 
in the Moray Firth, especially in comparatively shallow water, as at 
Guillam Bank, in 8 to 10 fathoms. 
CIROLANIDA. 
Cirolana borealis, Liiljeborg. 
A specimen of Cirolana borealis occurred in a gathering collected by the 
“St. Andrew” to the eastward of Fair Island on October 12th. The 
same species has also been obtained by the ‘‘Garland” off the coast of 
Caithness and in the Clyde. Rev. A. M. Norman records it as not 
uncommon on the “Haddock Ground” near Whalsey Skerries, and in 
St. Magnus Bay, Shetland.
