124 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL.10 



Pectinate setae are present anteriorly, at least 2 in the tenth parapodium, 

 their form and size much as in those far back (pi. 7, fig. 162). In the 

 thirty-eighth parapodium there are about 6 in a parapodium. Composite 

 hooks are most abundant anteriorly; they are distally bidentate (pi. 7, 

 fig. 157). Acicula are dark, thicker than the subacicular hooks, distally 

 straight or slightly curved, especially in more posterior segments. 



In the maxillary apparatus (pi. 7, figs. 159, 160), maxilla I (for- 

 ceps) has a single tooth on either side, maxilla II has 5 and 4 teeth, 

 maxilla III has 8 teeth left, none right, maxilla IV has 6 and 5 teeth. 



Distribution. — E. (N.J cariboea was first described from the West 

 Indian region, and has since been reported as Leodice culebra Treadwell 

 (1921, p. 49) from the Panama Canal Zone, and as E. gagzoi Augener 

 (1922, p. 45) from Colombia. Monro (1933, p. 63) records it from 

 Colon, Panama. The present collections extend the range to the Pacific 

 side, in the Gulf of California. The bathymetric range is intertidal to 

 20 fms.

Collections.— A 15-39 (3) ; A 35-39 (1). 



Total number of segments is about 110 (coll. A 15-39). Subacicular 

 hooks are first present at about the twenty-fifth to twenty-seventh setiger; 

 ventral pads are continued posteriorly to the twenty-fifth or twenty-sixth 

 parapodium. No branchiae are present on any segments. Prostomial an- 

 tennae are smooth and lack the indistinct annulation of E. (N.J cariboea 

 (above). 



Distribution. — Originally described from Bermuda, this species has 

 since been widely reported from the West Indian region (Treadwell, 

 1911; 1921; Hoagland, 1919, p. 576), and from Colon, Panama 

 (Monro, 1933). Present collections originate in Colombia and Trinidad, 

 in a few fathoms. 



Genus LYSIDIGE Lamarck, emend. Ehlers 

 Type L. ninetta Audouin and Edwards 



Lysidice differs from other genera of Eunicidae in having only 3 

 prostomial antennae when adult; branchiae and peristomial cirri are ab- 

 sent; setal structures and maxillary parts are much as in Eunice (above). 

 The prostomium has a pair of dark eyespots near the outer base of the 

 paired antennae.
