farther than any. It seems likely that this is but a more mature 

 specimen than any of the others. There is one most interesting itemi 

 in its description, however. Lendenfeld states the spicule fur was- 

 about 20 mm high. The very longest spicule he records is 23 mm 

 Jong. Not only do his tabulated measurements show that most of 

 the spicules involved were less than 20 mm, but he specifically says- 

 (p. 163) that there are spicules lying in it freely. It is hardly con- 

 ceivable that the nonattached spicules came from another sponge.. 

 We have here, then, proof of the shedding of spicules, and the great 

 thickness of the fur in this specimen is due, in all probability, to- 

 good fortune in not having had the loose extra layers washed or 

 shaken off. 



Lambe in 1892 (p. 72) records a sponge from Vancouver Island 

 as Cydonium Tmilleri Fleming. Lendenfeld says it is his hremana.. 

 Lambe in 1893 (p. 36) records another from Queen Charlotte Islands,.. 

 about 3° of latitude away, also as Cydonium inilllerL Lendenfeld 

 says it is his agassizii. Lendenfeld is probably correct in separating- 

 Lambe's from Fleming's species, but Lambe was probably quite- 

 right as to the identity of the two with each other. In fact, Lenden- 

 feld quotes the 1893 article in both respects and, but for a clew 

 given by his page references, gives every indication that he is talk- 

 ing about the same sponge in both cases. (See Lendenfeld, 1910, pp.. 

 113, 155.)
