SIGALEONID^J. 



Sthenelais fusca Johnson. 



Sthenelais fusca Johnson, Proc. Cal. Acad. Sci. (3), Zoology, I, pp. 185-1S6; 

 PI. IX, figs. 60-616, PI. X, figs. 64, 64 ? . 



Two examples from San Diego and one from Chinatown Point, 

 August 12, 1904. 



One specimen is 110 mm. long with 172 pairs of elytra; the other is 



about the same size, but the number of elytra was not counted. The 



first mentioned has a caudal regenerating region of about a dozen 



segments, so that it is probable that the species reached a considerably 



larger size than the original description indicated. The first pair of 



elytra is pale and without markings, the others are of a darker brown, 



thickly and finely mottled with a reticular pattern of black. The 



pygidium, which was not described by Johnson, bears a pair of subanal 



cirri about as long as the last six or seven segments and of slender, 



tapered form. The distal papilla? of both rami of the parapodia are 



frequentty more numerous than indicated in Johnson's figure. 



Peisidice aspera Johnson. 



Peisidice aspera Johnson, Proc. Cal. Acad. Sci. (3), (Zool.), Vol. I, pp. 1S4, 

 185; PI. IX, figs. 56-59; PI. X, figs. Q3a-d. 



A single specimen with twenty-one pairs of elytra, dredged at Del- 

 monte wharf, vicinity of Monterey Bay, on July 12, 1904, represents 

 this species in the collection. 



AMPHINOMID^E. 

 Eurythoe californica Johnson. 



Eurythoe californica Johnson, Proc. Calif. Acad. Sci. (3), Zoology, I, pp. 1S4, 

 185; PI. IX, figs. 56-59, PI. X, figs. 63-63c/. 



This species is represented in the collection by about a dozen speci- 

 mens from San Diego and a single one from Monterey Bay, collected 

 on July 12, 1904, from the "point above Third Beach." 



Johnson gives no account of the proboscis, and as one of the 

 specimens has it protruded the following brief description is added. 

 It is about 3 mm. long and 1.8 mm. in diameter, subcylindrical, but 

 slightly compressed and slightly wider distally than at the base. It 

 terminates in a firm elliptical disk, with a vertical slit open ventrally 

 and a central depression in which the mouth lies; surrounding this 

 disk is a low annular fold. The cuticle is everywhere smooth, without 

 papillse, jaws or teeth of any kind.
