NO. 1673. RECEXT CRICOIDS FROM THE PHILI ri'IXES— CLARK. 393 



Color. — Chrome yellow, with numerous longitudinal narrow lines 

 on the radial and division series, and transverse lines on the arms, of 

 (lark brown. 



Type.— Cat. No. 254G9, U.S.N.M., from Albatross station 5108; 

 west of Nasugbu Point, central Luzon (east of Simo Bank) ; 16 

 fathoms. 



This delicate little species appears to be quite distinct from any of 

 those heretofore described; the absence of regular division series be- 

 yond the III Br, these last being 2 (l-j-2), are sufficient to distin- 

 guish it at once. Though very small, the type-specimen has the 

 appearance of being fully developed. 



PHANOGENIA DELICATA, new species. 



Centro-dorsal large, discoidal, with a broad flat polar area 5 mm. 

 in diameter; cirrus sockets in a single, slightly irregular, marginal 

 row. 



Cirri XIII-XIX, 24-25, moderately stout, 20 mm. to 25 mm. long; 

 first joint about twice as broad as long, the following gradually in- 

 creasing in length to the fourth or fifth, which is as long as broad; 

 next three or four joints one-third to one-half again as long as broad; 

 following joints decreasing in length, the terminal fourteen or fifteen 

 being about twice as broad as long; the second and following joints 

 Iiave their distal dorsal edges slightly prominent; after the seventh 

 or eighth, which is a well-marked transition joint, the distal dorsal 

 edge becomes strongly produced and finely serrate, this production 

 very gradually narrowing anteriorly, at the same time gradually 

 becoming crescentic, and gaining in height; the antepenultimate joint 

 bears a subterminal transverse ridge, bending forward on each side 

 as it decreases in height; opposing spine small, median, erect, trans- 

 versely elongate, not reaching one-fourth the dorso-ventral diameter 

 of the penultimate joint in height; terminal claw longer than the 

 penultimate joint, moderately stout, evenly tapering, and moderately 

 and evenly curved. 



Ends of the basal rays visible as small tubercles in the angles of 

 the calyx, bridging over the narrow clefts between the centro-dorsal 

 and the primary division series; radials only very slightly visible 

 over the ends of the basal rays ; I Br^ almost entirely, or quite, con- 

 cealed, very short, almost entirely united laterally; I Br, (axillary) 

 broadly pentagonal, twice as broad as long, the anterior angle rather 

 produced, the lateral edges free; II Br 4 (3+4), well separated 

 laterally; II Br, united for the proximal two-thirds, separated by 

 a broad U-shaped gap distally ; III Br 2, very rarely 4 (3+4). 



Arms thirty or thirty-one, slender, 70 mm. to 80 mm. long; first 

 two brachials approximately equal, slightly wedge-shaped, about 

 twice as broad as the median length, the first almost entirely united
