PROTO GOODSimi. 43 



concave, and frequently furnished with one or two sub- 

 meinbranous hollow sacs. This latter feature (if our 

 experience has not deceived us) is present only after 

 death. We have observed this structure only in this 

 family, and Dana has likewise figured it. The palm is 

 armed near the base and distal extremity with two small 

 teeth ; the finger is much curved, and its extremity 

 alone impinges against the palm. The third pair of legs 

 are rather longer than the second, and have the hand 

 serrated and furnished with a few cilia. The fourth pair 

 are like the third, but shorter ; the fifth are still shorter. 

 The sixth and seventh are long and powerful, having the 

 wrists, as well as the hands, furnished with uneven teeth 

 and a few hairs. The tail is very rudimentary, and sup- 

 ports in the male a single pair of rudimentary propoda. 

 The branchiae are attached to the second, third, and 

 fourth pairs of legs. 



This species has been named in honour of the lamented 

 Mr. Goodsir, who promised fairly to distinguish himself 

 in this branch of Natural History. It appears to be a 

 northern species, since we have received it only from the 

 Moray Frith, through the kindness of the Rev. George 

 Gordon, from the Shetlands, where it was dredged by the 

 Rev. A. M. Norman, and who also has found it on the 

 coast of Durham.
