EMBLETON'S GALATHEA. 205 



latter in the comparative length of the joints of the ex- 

 ternal pedipalps or foot-jaws, of which the second joint is 

 longer than the third ; the spines of the rostrum are more 

 flattened than in the other species. Mr. Embleton states 

 that the " ligament of the shell " differs in colour in the 

 three species, being bright blue in G. strigosa, brown in G. 

 nexa, and blackish in G. squamifera. 



There can be no doubt of the distinctness of this species. 

 The characters above named are very constant, and the 

 habitat is essentially different. It is also by far smaller 

 than either of the others, as I have seen many now from 

 various localities, none of them exceeding that figured by 

 Mr. Embleton, and most of them much smaller. I have 

 one specimen, with spawn, of which the thorax and 

 abdomen together are not more than an inch in length. 



It is doubtless a deep sea species. Mr. Thompson's 

 specimens which I have before me, were obtained " from 

 the stomachs of cod-fish brought from the coast of Down 

 and Antrim to the Belfast market ; and in Dr. Drum- 

 mond's collection are specimens which were similarly pro- 

 cured." I have several specimens which were taken by 

 Mr. McAndrew in dredging in Loch Fyne at a depth of 

 from twenty to seventy fathoms, and by that gentleman 

 and Professor Edward Forbes at Zetland.
