PSAMMOLYCE FLAVA. 189 



Psammohjce flava Kinberg *). 



Siboga-expedition, Stat. 5, anchorage of Djangkar (Java), 

 at a depth of 330 M. A single incomplete specimen, 

 measuring about 50 mm. in length, with 90 segments. 



Though Ps. flava, according to Kinberg, at first was 

 found in the Atlantic near Rio Janeiro, I do not hesitate to 

 identify the Siboga-specimen with that species, on account 

 of the characteristic shape of its neuropodial setae ^). For 

 the appendix of those bristles somewhat resembles the bill 

 of a grallatory bird, being long, acuminate, faintly bent, 

 with a median fissure till about the middle of its length ; 

 they quite agree with the description and figures of Kin- 

 berg, only some transverse ridges of the shaft in the 

 neighbourhood of its distal extremity are overlooked by 

 him. The joint between the shaft and the appendix is not 

 always very obvious ; even in some of the setae it is 

 totally wanting and then both are melted together. The 

 appendix in the superior, the inferior and the median 

 bristles of this fascicle does not show such differences in 

 length as in other species of the genus. The neuropodium 

 of the second segment possesses setae of the same kind, 

 but they are more slender and the spinous rows of the shaft 

 are more strongly developed; moreover this neuropodium 

 bears at its distal extremity, besides the usual filiform 

 papillae, a long cylindrical appendage, with a club-shaped 

 end. With regard to the prostomium I found in the Siboga- 

 specimen the palpi not so long as figured by Kinberg; 

 they hardly extend beyond the distal extremity of the setae 

 of the buccal segment. The tentacle is absent. Kinberg 

 mentions two large eyes at the base of this organ ; he says, 

 they are „parum conspicui", but I could not detect them.

2) Also in other zoological groups examplos of such a wide geographical 

 distribution are to be found; Hoek f. i. mentions, that Poccilasma carinatum 

 and Scalpellum acutum are dredged in the Malay Archipelago as well as in 

 the Atlantic (The Cirripedia of the Siboga-expedition, pp. XIII and XIV).
