 pi. 1 3, fig. 25. Not uncommon ; differs from either of the pre- 

 ceding in the extreme length of the first pair of claws. 



22. GALATHEA nexa, nova species. Three specimens of this hitherto 

 unnoticed species have only yet been found, two in Berwick Bay, 

 and the other in Embleton Bay. It forms a beautiful link between 



G. sqttamifera and G. spinigera, approaching to the first in the 

 shape of the body, and to the latter in the shape and size of the 

 claws. The characters of the three species may be thus expressed : 



(1.) Gal. spinigera. Arms rather small, flattened, hirsute, very 

 spinous ; the spines arranged along each margin, and a row 

 of lesser ones down the middle ; ligament of the marbled 

 shell bright blue. 



(2.) Gal. nexa. Arms large, hirsute ; the hand without spines, 

 the wrist with a single one on the inner side, or, when two, 

 the anterior is much the smallest ; ligament of the shell 

 brown (plate 1). 



(3.) Gal. squamifera. Arms large, almost naked ; the hand 

 without spines ; two unequal spines on the inner side of the 

 wrist ; the posterior spine one-half less than the anterior ; 

 ligament of the shell blackish. 



23. NEPHROPS norvegicus, Leach, Mai. Brit. tab. 36. Norway Lobster, 



Penn. Brit. Zool. iv. pi. 12, fig. 24. One of the most beautiful of 

 the Crustacea ; on the coast of Berwickshire, opposite to Cold- 

 brandspath, it is not uncommon, bnt is rarely swt farther south.
