PROTO GOODSIRII. 43 
concave, and frequently furnished with one or two sub- 
membranous 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 branchiz 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 
Rey. A. M. Norman, and who also has found it on the 
coast of Durham.
