Part III. — Twentieth Annual Report 



five specimens of a Bomolochus taken from the gills and gill-covers of 

 one of these Rocklings, appear to belong to a new species.* 



The annexed list contains the names of all the organisms observed : — 



List op Specibs in the Stomachs of Fivb-bearded Rocklings. 



Grbater Sand-eel. Ammodyteslanceolatus, Le Sauvage. 



Six Sand-eels from the Moray Firth, measuring 12^ cm. to 16| cm. in 

 length, and collected in June, 1900, were found to have been feeding largely 

 on Copepods, and the following species were recognised : — Pseudocalamis 

 elongatus, Temora longicornis, Ectinosoma sp. {^sarsi), Stenhelia sp., and 

 Lichomolgus sp. Larval Balani (cypris stage) were also of frequent 

 occurrence. A sample comprising four specimens which were sent from 

 Annan in April, 1900, had nothing in their stomachs that could be 

 identified. 



In the stomach of a speciruen from the Moray Firth (Smith Bank), 

 collected on June 5th, 1901, many pelagic Copepods were observed, and 

 they belonged for the most part to two species — Calanus fimnarchicus a.n& 

 Pseudocalamis elovgatus ; in this stomach no organisms other than the 

 Copepods were noticed. I have notes of a sample of ten specimens 

 collected on December 26th, 1900, but the locality where they are 

 from is uncertain. The length of these specimens ranged from 15| 

 cm. to 17| cm., and the stomachs of all of them contained food. The 

 food in three was not sufficiently perfect for identification, but the 

 contents of the others consisted almost entirely of pelagic Copepods, the 

 prevailing species being Temora longicornis. Calanus finmarchicus was 

 observed in one, and a number of specimens of Centropages typicus were 

 obtained in another stomach ; a young Mytiiis (?) edulis occurred in one, 

 and larval Balani (cypris stage) in one.f 



* This Bomolochus is described at p. 289 of the present Report, under the name of 

 Bomolochus onosi. 



t Van Beneden states [Les Poissons des Cotes de Belgique, p. 64) that the food of the 

 closely-allied species, Ammodytes tobianus consists also of microscopic Crustacea.
