1 The species of this genus [Sergestes] mostly live within 100 fathoms of the surface, hut there is every reason to 

 believe that this one [Sergestes 'profundus] resides near the bottom. — (Spence Bate, Zool. Chall. Exp., part 52, p. 429.) 



2 A certain amount of variation is noticeable in specimens [of Parapagurus abyssorum] from different localities, 

 more especially as regards the amount of pubescence and granulation on the chelipedes and ambulatory limbs. In a 

 specimen from Station 133 [South Atlantic], the ophthalmic scales are bidentate, and the external prolongation of the 

 second antennal peduncular joint is dentate. In spite of these apparent incongruities, an examination of the numerous 

 specimens taken by the Challenger has convinced me that they all belong to a single species. . . . Parapagurus 

 abyssorum is of special interest on account of its very extended distribution and deep-water habitat. It was taken by 

 the Challenger in all the great ocean beds explored (with the exception of the Southern Ocean between the Cape 

 and Australia), and nowhere in less than 1000 fathoms of water. [This species is recorded from Magellan Strait, 

 45 fathoms, but Henderson maintains that this is an error ; he says that a shallow- water habitat for the species is 

 quite out of the question.] It appears to be invariably associated with an Anemone which exerts a solvent action on 

 the Gastropod shell originally selected as a dwelling-place by the Hermit ; in many cases the shell has entirely 

 disappeared, and in others it is greatly reduced, while the Anemone forms a soft and saccular covering on the 

 exterior. — (Henderson, Zool. Chall. Exp., part 69, p. 88.) 



3 The single specimen [of Tylaspis anomala] came from the greatest depth at which any Anomurous Crustacean 

 was taken by the Challenger. The form of the abdomen points to the sjiecies having occupied some other 

 dwelling-place than the Gastropod shell usually selected by the soft-tailed Pagurids. — (Henderson, Zool. Chall. Exp., 

 part 69, p. 81.) 



4 This true deep-sea species [Colosscndeis brevipes] was dredged from the greatest depth at which a Pycnogonid has 

 been found, viz., 2650 fathoms. — (Hoek, Zool. Chall. Exp., part 10, p. 72.) 



4 I believe this species [Nymphon longicoxa] with its rudimentary eyes to form the transition from the shallow- 

 water species to the true deep-sea species. . . . Nymphon longicoxa and Nymphon compactum were obtained [at the 

 same Station] from a depth of 1100 fathoms. N. longicoxa shows rudimentary eyes, those of N. compactum are quite
