Part III. — Sixteenth Annual Report 



(i.) The Euphausiidce. 



Boreophausia raschii. The records of this species are comparatively 

 few, and are all included in the statistics for 1889 and 1890. In 1889 

 there are eleven records of this species, one each for Stations I., III., and 

 ly. in January, one each for Stations I. and V. in February, and one 

 each for all the six stations in November. There are three records for 

 1890, one each for Stations I. and VIII. in February, and one for Station 

 IV. in March. 



Tliysanoessa neglecta. This is the Schizopod that is usually referred 

 to in the records as " Thysanoessa sp." It was observed in 1891 at 

 Station III. in October, and again at the same station in November ; it 

 was also observed in November at Stations Y. and VIII. In 1892 the 

 records for Thysanoessa are as follows : — For Station I. in September, 

 and again in November and December ; for Station III. in December, and 

 in the same month at Station IV. ; at Station V. in October, and again 

 in November and December ; once at Station VIII. in October, and on 

 two different occasions in December (on one of these occasions the species 

 was observed in both the surface and bottom tow-nets) ; at Station IX. 

 it was also taken twice in December, one on the 2nd and again on the 

 22nd. There are only two records for Thysanoessa in 1893 — viz., in 

 January for Station III. and in September for Station I. The only 

 records in 1894 are two in December, when the species was taken in 

 both the surface and bottom tow-nets at Station III. In 1895 there 

 is no distinct record for Thysanoessa, and it probably was not observed 

 during that year. 



(w.) The My sides. 



Siriella jaltensis. (This is equal to S. crassipies. G. 0. Sars, of earlier 

 papers.) There is but one record for this among the faunal lists for the 

 seven years; it was obtained at Station V. in March 1893. 



Siriella armata is another species that is seldom met with in the Firth 

 of Forth, and only one record of it is published in the lists of tow-net 

 fauna of the selected stations; it occurred at Station III. in March 1892. 



Gastrosaccus spinifer. There are records of this species from one 

 or other of the selected stations for all the seven years except 1891. 

 The hrst record is for Station VIII. in November 1889. In 1890 the 

 species is recorded for Station VIII. in December, and for Station IX. 

 in August. In 1892 for Station I. in January, and Station V. in 

 March. There is only one record in 1893 — viz., for Station I. in 

 January, and one in 1894 for Station III. in February. In 1895 there 

 are two records, one for Station ILL in February, and one for Station 

 VIII. in December. 



Heteromysis formosa is one of the rare species recorded for the Firth 

 of Forth, and has only been observed twice during seven years — viz., at 

 Station I. in August 1894, and at Station IV. in February 1895. 



ErytlLrops gu'esii. This Mysid, though not known to occur in Britain 

 previous to the institution of the Board's scientific investigations, is the 

 most common of the Mysidae in the seaward part of the Forth estuary, 

 and there are several records of it for all the selected stations. In 1889 it
