The San Diego specimens are noteworthy for the very conspicuous 

 notopodial spots and in one case for the equally conspicuous spots on 

 the pygidium. The example dredged at Monterey is filled with small 

 eggs and has the eyes enlarged, but is not otherwise modified. 



EUNICID^E. 

 Eunice (Eriphyle) paloloides sp. nov. (Plate VII, figs. 5-7). 



The type of this species is a nearly complete worm closely related 

 to the celebrated "palolo" (Eunice viridis) which it resembles in 

 form. It consists of a thicker anterior non-sexual region of about 

 200 segments and a slender posterior sexual region of more than 550 

 segments. Owing to the softening of a portion of the worm the exact 

 point of transition cannot be determined and accurate measurements 

 cannot be given. The size and proportions, however, closely approxi- 

 mate those of E. viridis. 



Prostomium (somewhat distorted by protrusion of the jaws) about 

 twice as wide as long, broadening anteriorly where it is divided into 

 two s*hort, wide, broadly rounded lobes by a shallow emargination 

 which continues caudad as a dorso-median furrow; a transverse fur- 

 row passes across the posterior ventral part of each of these frontal 

 lobes. Five tentacles arranged in a nearly straight transverse line, 

 the middle one being slightly behind the others and in contact with the 

 nuchal fold. Middle one slightly the longest (H times length of 

 prostomium), the lateral shortest and separated from the second pair 

 by a wider space than separates the latter from the median. All 

 regularly tapered and transversely wrinkled, but not beaded or articu- 

 lated. Eyes conspicuous, with large lenses, situated between the 

 outer and inner paired tentacles close to base of latter. On one side 

 a rather conspicuous pigment spot lies just anterior and external to 

 the lateral tentacle. 



Peristomium a slightly swollen naked ring considerably longer than 

 the prostomium and forming a distinct nuchal fold dorsally, but little 

 swollen laterally. Somite II is a short, simple, apodous ring bearing, 

 close to the anterior border, and on a level with the lateral tentacles, 

 a pair of short conical nuchal cirri slightly longer than the segment. 



Segments of anterior region very short, flattened and concave 

 below, at first strongly arched above but gradually becoming flatter 

 and more depressed. Owing to the poor preservation of the segments 

 following CC it is not possible to determine at just what point the epi- 

 tokous sexual region separates, but a marked softening of the tissues 

 and the enlarged size of the neural eye-spots (phototactic organs) on
