tooth, the posterior of the five which occupy the hitero- 

 anterior margin ; of these teeth the middle one is broader 

 than the others, and the posterior is much longer ; they 

 are all somewhat curved forwards. The anterior portion of 

 the carapace is minutely granulated, and has several slight 

 elevations ; the front is slightly four-lobed, the division 

 more strongly marked in the male. The first pair of legs 

 strong and angular ; the wrist having a strong tooth on 

 the inner anterior angle ; the hand with two carina3 above, 

 the inner one terminating in a small spine. The moveable 

 finger with three distinct longitudinal carinas, and deep 

 intermediate grooves. The three following pairs of feet 

 long and slender, increasing in length to the fourth, which 

 is the longest of all ; flattened, the last three joints lon-

 terminal joint lanceolate and slightly grooved. The ab- 

 domen, in the male, triangular, the last joint abruptly 

 narrowed ; in the female, broad and much rounded. 



The colour of this species is a rich deep brownish red, 

 with reddish grey spots; the abdomen yellowish or pinkish 

 white.

 our southern coast is interesting, as affording another in-

 to which I have already had occasion so repeatedly to 

 refer. It had not, I believe, been found on our shores until 

 it was dredged on the coast of Cornwall in the year 1848, 

 by my friends Prof. E. Forbes and Mr. M'Andrew, from 

 whom I received a male specimen, and subsequently, 

 through the kindness of Mr. Cocks of Plymouth, a female, 

 which was taken by that gentleman. I also received 

 a specimen from Mr. R. Q. Couch, of Penzance, during 

 the year above-mentioned. It is doubtless the species
