Dorvillea moniloceras (Moore) 1909 

 Redondo en, axis, in 282 m (3). 



Dorvillea atlantica (Mcintosh) 1885 



Coronado en, in 344 m (7). This is a long, linear species measuring 

 35 mm long by 1.7 mm wide. The prostomium has a pair of large 

 eyes, located in front of the articulated antennae, and a pair of much 

 smaller ones near the posterior margin of the lobe. The long dorsal 

 cirrophore is penetrated by a slender aciculum. The neuropodium is 

 distally truncate and shortest along its dorsal edge. The ventral cirrus 

 extends beyond the setigerous lobe. Dorsalmost neuropodial setae are 

 furcate spines accompanied by long, slender capillary setae. The com- 

 posite falcigers have an appendage in which length/width proportions 

 are in the ratio of 20 to 40.1, considerably longer than those typical of 

 Dorvillea atlantica, from the Atlantic Ocean (see Fauvel, 1923, p. 

 449). 



This is the first record of the species from the eastern Pacific Ocean.
