 Brada sp. ? juv. 



Two small specimens dredged at a depth of forty feet at San Diego 

 are considered to be the young of a species of Brada or possibly of a 

 Trophonia in which the anterior setse have not yet elongated. They 

 are about one-half inch long, clavate, with well-marked, simple seg- 

 ments, a few of which have been lost, thickly and uniformly covered 

 with papillae both dorsally and ventrally, those in the neighborhood 

 of the parapodia scarcely longer than the others. All setse are short, 

 only the notopodials of II being noticeably longer than the others. 

 On other segments both notopodial and neuropodial tufts consist of 

 a very few small, slender, tapered, flexible setse composed of numerous 

 joints which are always considerably longer than the diameter of the 

 seta. Neuropodials are no stouter than notopodials. The setse differ 

 from any species of Brada or Trophonia examined by me, but the 

 differences are such as might be expected in juveniles.

 p. 416; PI. 12, figs. 122, 123. 



Two specimens dredged at Delmonte wharf, Monterey Bay, July 12, 

 1904. 



The larger one has the head protruded. The mouth is a transverse 

 crescentic slit bounded below by a flat, slightly bilobed lip and above 

 by the slightly arched and thickened prostomium which bears the two 

 thick palps, grooved below, and above them eight tentacles in a trans- 

 verse series; the latter are about one-fourth as thick as the palps 

 and slightly exceed them in length. The small specimen is only 16 

 mm. long with 36 segments, badly abraded and nearly smooth except 

 the anterior four segments which are encased in a coating of agglu- 

 tinated sand grains. This may possibly be a distinct species. 



Trophonia capulata sp. nov. (Plate IX, figs. 60, 61). 



This very distinct species is represented by the type only, which 

 measures, exclusive of the cephalic setse, 108 mm. long, the cephalic 

 setse being 9 mm. and the maximum diameter at the end of the first 

 fourth 5.5 mm. Number of segments 136, the first achsetous. Form 

 elongated clavate, somewhat depressed at anterior end, subterete 

 at middle, becoming gradually subquadrate posteriorly. Anterior 

 half moderately stout, the posterior slender and gently tapered. 

 Ccelom containing many large free eggs. 



Prostomium and peristomium completely retracted within first 

 setigerous somite, leaving a small opening directed somewhat ventrad
