CRUSTACEA OF NORTHUMBERLAND AND DURHAM 



In ^^ga bicariiiata Leach the eyes are widely separated, in 

 ^^ga Strxmii they meet each other. Bate and Westwood 

 (vol. ii., p. 281) erroneously regarded the ^^^go- moiiophthalnia, 

 smaller form, as a variety to ^iiga tridens Leach. 



A specimen is in A. M. N.'s collection which was taken at 

 )Vhitburn, May 18, 1849, by Mr. Abbs, and given to Mr. 

 Hancock, who kindly added it to A. M. N.'s collection. A 

 second specimen is in the Newcastle Museum. Bate and 

 Westwood (vol. ii., p. 280) erroneously referred the Whitburn 

 specimen above-named, which was sent to them for their use, 

 to ^Ega bicariiiata. N.D.
