1869. Archi.ru s affinis, G. O. Sars, Nye Dybvands- 

 crustaceer fra Lofoten. Chr. Vicl. Selsk. Forh., p. 163 

 (p. 19 separate copy). 

 1897. Astacilla affinis, G. O. Sars, Crust. Norway, vol. ii., 

 Isopoda, p. 90., pi. xxxvii., fig. 2. 

 Dr. Henderson has recorded the occurrence of this species 

 in the Firth of Forth, which is the locahty whence the types of 

 Goodsircame; he writes, "N.E. of Inchkeith in the Firth of 

 Forth, April, 1884, attached to spines of Echinus escnlentus. 

 Colour pale white, transparent, the distal end of joints of 

 antenna banded with green ; green bands (faint) on anterior 

 segments of body." This observation is interesting in con- 

 nection with the fact that this Astacilla was taken in consider- 

 able numbers near the Fame Islands in 1863 clinging to the 

 test of Strongyldcentrotus drabachiensis (Miiller). The year 

 previously this species had been taken off Tynemouth (A.M.N.)
