 THE UNITED STATES FISHERIES STEAJMER "ALBA- 

 TROSS" IN THE VICINITY OF THE PHILIPPINE ISLANDS.

The third consignment of crinoids received from the U. S. 

 Fisheries steamer Albatross, collected during her cruise among the 

 Philippine and neighboring islands, proves to be much more inter- 

 esting than either of the two previously received. In the first place 

 it is very rich both in individuals and in species, being much the 

 largest collection ever received from any single area; secondly, it 

 contains a remarkable proportion of hitherto unknown forms. 



Altogether fifty-nine species are represented, of which twenty-four 

 are new; five- have been rediscovered for the first time since the 

 Challenger' collected them between October, 1874, and January, 

 1875, and one has been found which has not been collected in the 

 Philippines, from which locality the type was described, since 1866. 

 Numerous species of which I gave preliminary diagnoses from mate- 

 rial obtained by the Royal Indian Marine Surveying Ship Investiga- 

 tor have again come to light, and one of them, known previously 

 from only a single example, proves to be abundant. 



On the other hand, forty species previously secured by the Alba- 

 tross in this region are not represented, and six species originally 

 described from the Philippines by Carpenter jet remain to be redis- 

 covered. 



As we know it to-day the comatulid fauna of the Philippine Archi- 

 pelago comprises about one hundred and five species, while the facts 

 known in regard to the adjacent seas indicate the occurrence there 

 of two or three score more. I
