Suiiaris(i\s jia<jun\ Hesse. 



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

 was captured in the Cnmiarty Firth in September last ; it 

 occurred in material dredi^eil near Invergorden, and although 

 it was not taken on a Iiermit-crab, or in tlie shell occupied by 

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

 material in which it was obtained. The Cromarty Firth 

 specimen measures 2*8 millim. {■^\ of an inch). The ter- 

 minal claws with which the powerful anterior antenna} are 

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

 spines on the inner brandies of the second pair of ssvimming- 

 teet. Lonijipedina pacjuri, W. Miiller, is very likely the 

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

 specimen agrees better with Miiller's figures than with those 

 of Hesse ; but we have adoj)ted Hesse's name as having 

 priority over that of W. Miiller. 



A M P u I r D A. 

 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-iast 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 tooth 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. 



Ampkilochoides pusillus, G. O. Sars. 



Several specimens of this Amphipod have been obtained 

 by us in material from tiie 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 dactyli, of the first gnathopods, and by the inner margin 

 of the hand of the same gnathopods being distinctly angular ;
