540 PYCNOGONIDA 



Pallas, 1766); the type is P. littorale, Strom, of the 1ST. Atlantic 

 (0-430 fathoms), to which species have also been ascribed forms 

 from various remote localities, e.g. Japan, Chile, and Kerguelen. 

 P. crassirostre, G. 0. Sars, a northern and more or less deep-sea 

 form, is distinct, and so also are P. nodulosum and P. pusillum, 

 Dohrn, from Naples. P. stearnsi, Ives, from California, is like 

 P. littorale, except for the rostrum, which resembles that of 

 P. crassirostre. P. magellanicum, Hoek, P. nKujnirostre, Mobius, 

 both from the Southern Ocean ; P. microps, Loman, from Natal, 

 and four others described by Loman from the East Indies, are 

 the other authenticated species. Of P. philippinense, Semper, 

 I know only the bare record ; and P. australe, Grube, is de- 

 scribed only from a larval form with three pairs of legs. 

 P. orientals, Dana (first described as Astridium, n.g.), is also 

 described from an immature specimen, and more resembles a 

 Pli oxichilus. 



The British Pycnogons. 



Dr. George Johnston, 1 the naturalist-physician of Berwick-oil- 

 Tweed, Harry Goodsir, 2 brother of the great anatomist, who 

 perished with Sir John Franklin, and George Hodge 3 of Seaham 

 Harbour, a young naturalist of singular promise, dead ere his prime, 

 were in former days the chief students of the British Pycnogons. 

 Of late, Carpenter 4 has studied the Irish species ; and the cruises 

 of the Porcupine, Triton, and Knight Errant have given us a 

 number of deep-water species from the verge of the British area. 



In compiling the following list, I have had the indispensable 

 advantage of access to Canon Norman's collection, and the still 

 greater benefit of his own stores of endless information. 5
