new and rare Crustacea from Scotland. 147 



Sunaristes paguri, Hesse. 



A single specimen (a male) of this rare and curious species 

 was captured in the Cromartj Firth in September last ; it 

 occurred in material dredged near Invergordon, and although 

 it was not taken on a hermit-crab, or in the shell occupied hy 

 a hermit-crab, several Iiermit-crabs were observed in the same 

 material in which it was obtained. The Cromarty Firth 

 specimen measures 2*3 millim. (-j^ of an inch). The ter- 

 minal claws with which the powerful anterior antennee are 

 armed are of a dark horn-colour, and so also are the large 

 spines on the inner branches of the second pair of swimming- 

 feet. Longipedina paguri, W. MUUer, is very likely the 

 same species as that described by Hesse ; and in fact our 

 specimen agrees better with Mtiller's figures than with those 

 of Hesse ; but we have adopted Hesse's name as having 

 priority over that of W. Miiller. 



Amphipoda. 

 Harpinia crenulata, Boeck. 



A few specimens of this Harpinia have been obtained in 

 the Moray Firth and in the Firth of Forth. The more pro- 

 minent and distinctive characters of the species appear to be 

 the following : — The second-last pair of pereiopods are very 

 long, and, when bent backwards, extend considerably beyond 

 the body of the animal ; the posterior expansion of the basal 

 joint of the last pair of pereiopods has the margin irregularly 

 serrate and furnished with several comparatively long hairs; 

 and the last pair of epimeral plates of the metasome have the 

 lower distal angles rounded and furnished posteriorly with a 

 single small tootii or with two or three small teeth of unequal 

 size. But the long second-last pair of pereiopods seem to be 

 in themselves a very obvious character, and one by which 

 the species may be readily distinguished. 



Ampliilochoides pusillus, G. 0. Sars. 



Several specimens of this Amphipod have been obtained 

 by us in material from the Firth of Forth and from St. 

 Andrews Bay. The Forth specimens were dredged in the 

 vicinity of the Bass Rock in twenty-two to twenty-three 

 fathoms. This species is readily distinguished from Amphi- 

 lochoides odontonyx (Boeck), which has already been recorded 

 for the Forth, by the absence of a basal tooth on the claws, 

 or dactylij of the first gnathopods, and by the inner margin 

 of the hand of the same gnathopods being distinctly angular ;
