112 THE ANNELIDA POLYCHAETA. 



slender much as in P. fakaravana. The number of somites is about four 

 hundred. The styles of the dorsal cirri throughout, though at present much 

 shrivelled, seem clearly to have been of an ovate-lanceolate form, with the 

 tips often prolonged and markedly acute. The neurocirri seem to have been 

 of a sublanceolate form, with tips rather slenderly acute. The proboscis, 

 fully protruded but evidently much shrunken, is 3 mm. long. About its 

 distal end is a circle of twenty-four papillae which are proximally swollen and 

 contiguous, and distally conical and acutely pointed. The papillose area at 

 the base is very short, the papillae rather long, not at all dense, irregularly 

 scattered. The dorsum anteriorly is a dark brown of a pronounced reddish 

 tinge, becoming lighter caudad and essentially yellow in the caudal region. 

 The somites in the anterior region are very short and strongly crowded; caudad 

 they soon become actually as well as relatively much longer. The venter has 

 a pronounced neural furrow. 



Locality. Marshall Islands. Depth 12 fms. 1899-1900. One specimen 

 which came up on the anchor. 



Phyllodoce sp. b. 



The single specimen of this species lacks the anterior end, though the num- 

 ber of missing somites is probably not large. The fragment is 43 mm. long. 

 Its maximum width, exclusive of the parapodia, is near 1.8 nam., and inclusive 

 of the parapodia and setae, 4.2 mm. The number of somites in the fragment is 

 nearly one hundred. The body narrows to a point at the caudal end, and the 

 somites immediately in front of the pygidium are very short and closely crowded. 

 It also narrows moderately at the anterior end. 



The general color of the body is light brown, without markings except a 

 vague paler median longitudinal line dorsally and one ventrally, the ventral 

 one the more pronounced. 



The somites in the middle region of the body are about twice as wide a 



long. 



The parapodia are long. The setigerous neuropodium is cyhndrical, at 

 the free end subconically narrowed and rounded. The setae are numerous and 

 spread out in the usual fan-like manner. The shaft of each is enlarged at the 

 distal end to form the socket for the distal blade, which is abruptly more slender, 

 ends in a finely pointed tip, and makes a considerable angle with the shaft at 

 the level of articulation. Nearly all the styles of the notocirri are missing from
