The following diagnoses of some new species of CiiTi])edia from the 

 Albatross Phili]>pine cruise are ]Hiblishcd in advance of the final 

 report on the collection. 



ALEPAS NAVIGATOR, new species. 



Type-specimen.— C&t. No. 38698, U.S.N.M. 



Type-locality. — Nogas Point, Panay, surface, on a large Disco- 

 medusa. 



Capitulum large, with, well calcified, sharply defined scuta, in form 

 of a band along the occludent margin, with a wide diverging ascending 

 branch above. First cirrus with two basal appendages, the other 

 cirri with one, except cirri ii and vi, which have none. Length of 

 capitulum, 30 mm.; greatest width of capitulum, 24; length of pedun- 

 cle, 25; diameter of peduncle in middle, 7; length of aperture, 16; and 

 length of scutum, 1 2 . 



ALEPAS SPECTRUM, new species. 



Type-spedmen.—C'Ai. No. 38699, U.S.N.M. 



Type-locality. — Nogas Point, Panay, surface, on Discomedusa. 



The tunic of the narrow capitulum is excessively thin, without any 

 trace of scuta or other plates, thereby differing from aU other known 

 species of Alepas. 



Length of capitulum, 12 mm.; breadth of capitulum, 6; length 

 of peduncle, 6. 



SMILIUM HORRIDUM, new species. 



Type-specimen.— C&t. No. 43467, U.S.N.M. 



Type-locality. — Albatross station 5250, Gulf of Davao, 23 fathoms. 



The capitulum is armed with 15 plates, those of the lower whorl 

 l)rojecting horn-like. It is covered with a thick yellowish cuticle in 

 which the outlines of the plates are rather indistinct. The scutum 

 is almost as broad as long, acute above, faintly marked %vith growth 

 lines. The tergum is triangular, with a process appended on the 



Proceedings U. S. National Museum, Vol. 42— No. 1904.
