270 Part III. — Nineteenth Annual Report 



second is only about half as long as the first one ; the penultimate joint 

 of the flagellum is distinctly longer 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 

 longiremis. 



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 Leptognathia 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 antenuules. 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. 0. Sars to be three-jointed.* Male 

 specimens appear to be very scarce. 



Tanaopsis laticaudata, G. 0. Sars. 



This Isopod, 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. 



CiROLANm&. 



Cirolana borealis, Lilljeborg. 



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. f
