514 Part III. — Tiventieth Anmicd Report 



noticed here because in the stomach of one of them, about 2^\ centi- 

 metres in length, I found a specimen of Conchcecia elegans, an Ostracod 

 only hitherto observed in Loch Etive on the West Coast, and very rarely 

 in the extreme North of Scotland. 



Sclnstomydi< spiritus was frequent in the stomachs of twelve specimens 

 collected off Aberdeen on June 10th, 1901 ; Crangon allmanni, Aplieriisa 

 borealis, and Gammarus lociiMa were very rarely observed, while the only 

 species belonging to the Copepoda ol;)tained was Pseudocalanns elongatus. 

 OihopJeura was observed in four of the stomachs and was moderately 

 common in three of them, while Annelid remains occurred in five. 



A sample of Whitings, collected about ten miles off Aberdeen on 

 September 3rd, 1901, jneasured from 10| to 19 centimetres in length. 

 One of these had nothing in its stomach that could be distinguished, but 

 the stomachs of four contained the following among other Crustacea : — 

 Pandalus monfagui, Psendocuma cercaria, Ccdlisoma crenata. Argissa 

 hamatipes, Megamphopus cornutus, Calanus finmarcMciis, Pseudoccdanns 

 elongahis, Temora longicomis, and Metridia lucens ; Sagitta, and some 

 other Annelids were also observed. 



Thirteen specimens from Aberdeen Bay, collected November 6th, 1901, 

 and measuring from 15 to 24^ centimetres, had very little food in their 

 stomachs ; Crangon vulgaris, jun., was observed in two ; so also were 

 Schistomysis inermis, Hyperia galba, and Garnmarus sp. (jun.). Remains 

 of Annelids were also observed in one or two of the stomachs, but any 

 food that was present was not very easily identified. The stomach of 

 one specimen, ^h centimetres, had a young flat-fish in its stomach, while 

 in the stomach of the flat-fish itself, Calamus and fragments of Bathy- 

 poreia sp. were obtained. The stomach of another specimen, 7 centimetres 

 long, contained Hyperia galba, Pseudoccdanns elongattis, and a few very 

 young Decapoda. 



Fourteen specimens ranging in length from 9 to 14 centimetres, besides 

 two at 15:? cm. and one at 17 cm., were captured in 68 fathoms about 

 9 or 10 miles off Aberdeen, in November, 1901, and the examination 

 of these gave the following results; the smaller specimens were found to 

 have been feeding chiefly on Paratheniisfo oblivia — nearly every one 

 of them having some of these Crustaceans in their stomach — the speci- 

 mens were somewhat immature, but they all probably belonged to the 

 species named ; a few other species such as Craiigon allmanni, Paratylus 

 sp., Temora longicomis, and Metridia lucens were also noticed. The 

 stomachs of two of the larger specimens were empty, but the other con- 

 tained fragments of two iSpiro7itocaris securifrons. 



Other twelve Whitings ranging from about 14 to 20 cm., collected 

 in Aberdeen Bay on November 29th, had scarcely anything in their 

 stomachs that could be identified ; but so far as the contents could be 

 made out, the fish appeared to have been feeding chiefly on Annelids ; 

 but a few fragments of species of Mysidje were also observed. 



Schistomysis spiriius was the most common species in the stomachs of 

 Bome Whitings captured off Collieston on July 5th, 1901 ; Psendocuma 

 cercaria occurred in four of these stomachs and was abundant in one of 

 them ; Batliyporeia norvegica was present in one and Oikopleura in six. 

 A few other common forms were also observed. 



Six specimens from Smith Bank, Moray Firth, measuring 20| to 27 

 centimetres, and collected June 5th, 1901, had very little in their 

 stomachs that could be distinguished. A female of Ampelisca assimilis 

 was about the only thing that could be satisfactorily determined ; while 

 the remains of small fishes, Annelids, and what seemed to be fragments 

 of a Crcmgon appeared also to form part of the food contained in these 

 stomachs — all being considerably decomposed.
