NO. 5 HARTMAN : POLYCHAETOUS ANNELIDS 501 



easily overlooked since the base may be partly overhung by the pygidial 

 ring. I am unable to account for the other 2 disparities, namely the 

 presence of 4 instead of 2 eyes, and the presence of furcate spines in the 

 superior, instead of middle, setal fascicle. These 2 characters alone 

 seem hardly sufficient to merit the erection of a new species for the 

 individuals herein described. 



J. gorgonensis Monro (1933, p. 50) is here believed to be conspecific 

 although the illustration of a median parapodium seems to differ. It is 

 possible that this figure was made from a preparation depressed under a 

 cover slip. The same effect has been produced with preparations from 

 individuals recorded herein. When not depressed the dorsal and ventral 

 cirri are fusiform and the neuropodium is less broad than shown; also, 

 the setae are disposed in a whorl, not in a vertical series. The dorsal 

 acicular spine is shown straighter for A. gorgonensis than is actually 

 the case, but they may have been seen only from the front. Fauvel ( 1923) 

 described the presence of a midventral groove which Monro (1933) said 

 was absent, but this character may be dependent on methods of fixation. 



The individuals recorded above were collected from sandy crevices at 

 El Descanso, Lower California, and in similar habitats at La Jolla, Cali- 

 fornia, both from low intertidal zones. 



Distribution. — The disjunct, though widely known records of this 

 species have been largely assembled by Fauvel (1932, p. 64). They 

 include the Red Sea, Indian Ocean, islands in the south Pacific Ocean, 

 and Curagao in the Dutch West Indies. Later Monro (1933) recorded 

 it from Gorgona Island. The present records are Lower California and 

 southern California.

Collections. — Lemon Bay, southern Florida, sandy shore ( 1 ) ; Beau- 

 fort, North Carolina, sandy shore (1) ; U.S.S. Albatross Station D 5821, 

 middle section of San Francisco Bay, California in 8-10 fms (2). 



A complete, though probably immature individual from Lemon Bay, 

 Florida, is 26 mm long and consists of 146 segments. It has the general 

 appearance of an abranchiate onuphid because of the long prostomial 

 antennae and tentacular cirri. The surface epithelium is smooth except 

 for a few scattered papillae on the dorsal sides of notopodia. The body is 

 depressed in its anterior half but thereafter tapers gradually and is some-
