Part III. — Twenty -first Annual Report 



one pair of jaws, the number of these molluscs which had been 

 recently captured by the King-fish would therefore amount to fifty-four. 

 A few of the jaws were of a moderately large size, but the majority 

 were apparently those of small specimens. Amongst the digested 

 matter contained in this stomach were also a few things that looked 

 like the partially-dissolved ^cartilaginous shells of Cuttlefishes, but they 

 were so imperfect that no use could be made of them for the purpose 

 of identification.* The jaws, after being mounted on a slide, were 

 photographed by Dr. Williamson, and the accompanying figure is repro- 

 duced from the photograph. 



Anarrhichas lupus, Lin. 



The stomachs of eight Cat- or Wolf- fishes were examined ; the sh 

 were captured in the Moray Firth on May 16th, 1902, and were all of 

 moderately large size. The following is a note of the contents of each 

 of the eight stomachs: — 



(1.) Fragments of a large Crab, Cancer pagurus, and of Ophiura sp. 



(2.) Part of a large Buccinum undatam, and several large speci- 

 mens of Ophiura eiliaris. 



(3.) Fragments of several large Soleji siliqua, the shell of a Natica 

 containing a small hermit Crab, and a specimen of Hijas 

 coardatus. 



(4.) Fragments of a moderately large Cancer pagurus, of Solen 

 siliqua, and of Cardium echinatum, and a specimen of Aphrodite 

 aculeata. 



(5.) Remains of Solen siliqua, Natica sp., Eupagurus bernhardus, 



and Hyas coarctatus. 

 (6.) Fragments of Eupagurus bernhardus, and of several Ophiunc. 

 (7.) Fragments of Natica sp., and Venus lincta, and of a large 



Eupagurus bernhardus. Eighty-two specimens of Star-fishes. 



Ophiura eiliaris (Linn.). Some fragments of Echinocardium sp. 



(probably E. cordatum). A specimen of Aplirodite acideata 



and a fragment of a Zoophyte. 

 (8.) Remains of five Natica sp., and of Littorina littorea. Tvro 



Eupagurus bernhardus, and forty-four specimens of Ophiura 



eiliaris, all more or less complete. 



Lumpenus lampetrmformis (Walbaum). 



The food observed in the stomach of a Sharp-tailed Lumpenus 

 captured on the Fisher Bank consisted almost entirely of smail 

 Crustacea, the following species of which were identified : — Leucon 

 nasica, Diastylis resima, Bythocythere simplex^ Macrocypris minna, 

 Cytheropteron sp,, and Robertsonia tenuis. Two specimens of 

 Cyclichna 7iitidula, and one or two Operculina ammoides, a species of 

 Foraminifera, were also noticed. The Lumpenus is a fish that appears 

 to live on or near the bottom, and it is to be expected that demersal 

 organisms rather than pelagic will constitute the chief part of its 

 food. 



* Dr. T. Wemyss Fulton, in his " Ichthyological Notes" in Part III. of the 

 Nineteenth Report of the Fishery Board for Scotland, also incidentally refers to the large 

 number of Cephalopod mandibles observed in the stomach of the King-fish.
