At the above-named Stations individuals of a Psammolyce-s^&d&s were met with, that 

 belong- to the group of Ps. armosa D. Ch.i) and in many regards agree with Willey's des- 

 cription of Ps. zeylanica, though some sHght diiïerences could be stated. The largest specimen 

 (of Stat. Ambon) measures about 100 mm. in length and its greatest breadth (with bristles) 

 amounts to 12 mm. Usually the ventral side of the body is hairy, though not more conspi- 

 cuously in the vicinity of the mouth, as f. i. is to be seen in Ps. malayana (see later on); even 

 in the specimens of Stat. Banda the anterior region of the venter shows so few fihform papillae, 

 except at the base of the parapodia, that with regard to this character the specimens more resemble 

 Ps. rigida Gr. (Willey, loc. cit. p. 256). Examined with high power the venter appears to 

 be coated with long, pointed, somewhat spinous processes, that are dilated at the base, whereas 

 small globular tubercles are situated between them. The first pair of elytra is elongated, roun- 

 ded triangular, with the internal border nearly straight; posteriorly the elytra become notched 

 and lobed, especially at the median side. Usually two lobes occur at the internal corner and 

 a large tubercle at the posterior margin. The anterior border of the elytra is smooth, but along 

 the posterior margin long filiform papillae are situated ; on the external border these are sepa- 

 rated in groups, whereas short, cup-shaped papillae occur in the intervals between them. The 

 scar of insertion is elongated, elliptical. The dorsum between the elytra is beset with rather long 

 filiform papillae, arising from the tip of a short common stem, like in Ps. armosa (St. Joseph. 

 loc. cit. pi. 2, fig. 26). The tentacle of the head has a terminal joint, which is at the most 

 one and a half as long as its basal part, and a trifle shorter than the tentacular cirri, whereas 

 according to Willey it should measure thrice its length. 



The first parapodium (PI. XXVII, fig. 7) shows great resemblance with that of Sthene- 

 lais, as elaborately described and figured by Pruvot and Racovitza -) ; besides the two tenta- 

 cular cirri, that are nearly of the same length, there occurs above the base of the dorsal one 

 of these (Fig. 7<^, /. t".), a third cirriform appendix, the lateral antenna (Tig. 7, /- «.). This appen- 

 dix is conical of shape, not quite as long as half the length of a tentacular cirrus and shows 

 near its base a faint constriction as if there exists a basal joint. At the internal side of the 

 parapodium a rounded rectangular praebuccal lamella and a triangular cuilleron céphalique are 

 visible ; moreover there are two bristle-fascicles, consisting of simple, capillary setae, whorled 

 and with a faintly curved tip. The dorsal fascicle only is furnished with an acicula. 



In the second segment the neuropodial fascicle consists of compound setae with plumose 

 shaft and .slender, elongated appendix, with filiform curved apex as figured by Willey, (loc.
