Thirty-three specimens have been examined, twenty being from the 

 Moray Firth and thirteen from the Firth of Forth. The Moray Firth 

 specimens were collected on December 25th, 1900, and measured about 

 9 to 1'6^ centimetres in length ; only nine of them contained food that 

 could be identified, and it consisted for the most part of Copepods. The 

 following are the species which have been satisfactorily determined : — 

 Galanus finniarchicus, observed in one stomach ; Pseudocalanus elongatus, 

 observed in one; Temora longicornis, in six; Acartia sp., in two; and 

 Oithona C?) lielgolandica, in two. 



The specimens from the Firth of Forth were collected in May of the 

 present year (1901), and with the exception of one specimen they were 

 all under four inches in length (about 8 to 9 cm.) ; the largest one 

 measured about 13| cm. The stomachs of all the thirteen specimens 

 were fairly well filled, but their food consisted almost entirely of pelagic 

 Copepoda. The most common species were Pseudocalanus elongatus, 

 Temora longicornis, and Centropages hamatus ; Calamts finmarchicus 

 was also present ia most of the stomachs, but was usually represented by 

 only a few specimens; Podon leuckartii, Evadne nordmanni, larval 

 Decapods, and larval Balani (both nauplius and cypris stages) were 

 occasionally observed. 



The names of the various organisms noticed are arranged in the 

 annexed list : —
