356 L. E. CRAWSHAY. 



not from E. tuberosa, as found by "Walker (136, p. 98), but from 

 E. crancM. E. tuberosa is readily distinguished from it, as from the 

 latter, by the more elongate " hand " in the first peraeopods, and also 

 especially by the much longer claws, both sexes showing these 

 characters alike. These points are mentioned by Montagu (126, 

 p. 86) in his original description of Cancer tumef actus, and figured 

 by Leach and by Bell, while the last author even expresses his inability 

 to account for the two species being confused with one another. Bell 

 (109), as he interprets the species, describes the meropodite or "arm" 

 of E. tumef acta {= E. hryeri) as not more than twice as long as broad, 

 and that of E. cranchi as three times as long as broad, using this, 

 moreover, as one of the distinctive characters between them in his 

 description of the latter species (109, p. 149). On this interpreta- 

 tion, while E. tumefacta is distinct in this appendage from E. tuberosa 

 by the shorter meropodite and propodite, it is separated from 

 E. cranchi by the shorter meropodite only. The number of specimens 

 of E. tumefacta I have seen, satisfactorily to be regarded as such, and 

 bearing out this character, is very few, and unless the species is 

 extremely local in its habitat, it is difficult to consider it as more than 

 a variety of E. cranchi. Dr. Allen's record of it as abundant to the west- 

 ward of the Eddystone (1) would support the former alternative, but in 

 this case some difficulty arises in the fact that the specimens concerned 

 showed a close similarity to E. tuberosa. In the absence of any clear 

 evidence to the contrary, it seems best to retain the species as distinct, 

 though probably it has often been confused with others in records of 

 the genus.
