developmental stages of the principal spicules. First microscleres, 

 palmate anisochelas (fig. 47, G) \ length, 15/x to 33/a. Second niicro- 

 sclere, bipocillates (fig. 47, E) ; length always very close to 15/a, the 

 shorter illustrations in the figure being end views. 



Remarks. — This form differs from the typical species in having all 

 its spicules, except the palmate anisochelas, somewhat smaller. 



Lambe (1898, p. 30) describes sponges from the Pacific coast of 

 Canada as lophon chelifei\ which should be regarded as synonymous 

 with the new variety. Wilson (1904, p. 143) records sponges from 





FiGUEE 47. — lophon chelifer Ridley and Dendy californiana, new variety : 

 E-G, X 1,333 ; others, X 300. F, above and below, spicules more sug- 

 gestive of anchorate chelas than of bipocillates. Such series as this, 

 very easily noted in microscopical preparations of lophon, point to the 

 pathogenic distortions of chelas 



the eastern troj^ical Pacific {Albatross Station 3384) as chelifer, 

 variety ostia-magna. This seems not so close to the Californian form 

 as Lambe's. The type of the species is from subantarctic waters 

 (Ridley and Dendy, 1886, p. 349).
