14 ALLAN HANCOCK ATLANTIC EXPEDITION REPORT 



3 pairs of elytra are oval ; therafter they are sharply incised at both inner 

 and outer lateral margins (pi. 2, fig. 9) ; in posterior segments, however, 

 the inner lateral margin is rounded (pi. 2, fig. 11). Parapodia are strongly 

 fringed, especially in anterior segments (pi. 1, fig. 2). A single long pa- 

 pilla on the notoacicular lobe projects beyond the others. The acicular lobe 

 is conical (pi. 1, fig. 1). Neurosetae are of two kinds, including a small 

 anterior-superior fascicle of spinose setae (pi. 1, fig. 4) and whorls of 

 composite setae with canaliculate appendage and pointed tip (pi. 1, fig. 3). 

 Distribution. — Originally described from Congo, Africa, it has been 

 reported from West Indian seas; this record extends the range to Cale- 

 donia Bay, Panama.

Sthenelais articulata Kinberg

Collection.— A 22-39 (1). 



An accessory ventral cirrus is present through 5 segments. Multiar- 

 ticulate hooks occur only in the superiormost series of neurosetae. The 

 ventralmost hooks are bounded below by a row of fringe. In the closely 

 related S. tertiaglabra Moore (1910, p. 395), to which S. hancocki Hart- 

 man (1939, p. 65) belongs, an accessory ventral cirrus is present only on 

 2 segments; multiarticulate hooks occur in number through the neuro- 

 podium, and there is no fringe on the ventral side of neurosetae. These 

 and other differences will be discussed more fully later. 



Distribution. — Brazil, tropical West Indian region; central eastern 

 Pacific, north to southern California.
