NO. 1 HARTMAN : POLYCHAETOUS ANNELIDS 121 



are strongly falcate ; maxilla II has 8 teeth on the left, 9 on the right side, 

 they increase in size distally and are more or less equally spaced from one 

 another except for slight irregularities. Maxilla III has 8 teeth left, the 

 third and fourth distalmost are the largest; maxilla IV has 7 teeth left. 

 On the right maxilla III (fused with IV) has 9 teeth; maxilla V has a 

 single tooth on either side. The formula is thus: 1-1, 8-9, 8-0, 7-9, 1-1. 



The tube is branched, bifurcated once or several times, covered with 

 a thin layer of mud or also fine gravel over a soft, chitinized base. A 

 portion, showing method of branching, is shown in pi. 8, fig. 174. Tube 

 fragments have been taken from stations 1133-40, 1272-41, and 1137- 

 40. 



E. americana comes near to E. indica Kinberg in having a strongly 

 branchiate region anteriorly; in both, the subacicular hooks are distally 

 tridentate, sometimes to 3 or 4 in a parapodium; also, both have long, 

 slender, smooth prostomial antennae. In E. americana, however, the com- 

 posite hooks terminate in a main tooth that is practically in a straight 

 line with the main part of the appendage, and is never falcate or bent as 

 in E. indica; the distal end of the subacicular hook is far less prolonged 

 in E. americana than in E. indica; the tube of the former is branched. 



Holotype. — AHF no. 45. 



Type locality. — Off Redondo Beach, California, in 136-172 fms 

 (1130-40). 



Distribution. — Off southern California, south to western Mexico, in 

 depths of 15-174 fms. 



Eunice schemacephala Schmarda 



Schmarda, 1861, p. 132, pi. 32, fig. 260, 7 text figs. 

 E. fucata Ehlers, 1887, pp. 91-93, pi. 25, figs. 8-20. 



Collection.— A 50-39 (2). 



This species is at once distinguishable from others of the genus in 

 that its subacicular hooks are dark and end in a simple, falcate tip ; they 

 are present usually singly in parapodia, from about the fortieth setiger. 

 Acicula are also dark, occur usually 2 in a parapodium. Branchiae are 

 present from about the fifth parapodium. 



Distribution. — Common in the West Indian region, Atlantic Pana- 

 ma, littoral.
