NO. 1 HARTMAN : GONIADIDAE, GLYCERIDAE, NEPHTYIDAE 127 



Setae consist of preacicular barred (figs. 7-10) and postacicular lan- 

 ceolate ones. Furcate setae have not been identified. The lanceolate setae 

 have transverse rows of serrations (figs. 5, 6). 



Most of the individuals listed above are anterior fragments or at 

 least not posteriorly complete. Since they are from dredged collections, 

 and sometimes in groups, it is suggested that they may form beds. Most 

 specimens come from green mud. 



A. erectans resembles A. malmgreni (Theel) in some respects. Both 

 have a proboscis with 14 rows of papillae and with 10 to 13 in a row 

 and both lack a large middorsal papilla. In both the acicular lobes are 

 conical and the postsetal lobes are inconspicuous; the interramal cirrus is 

 small or absent in a long anterior region. A. erectans differs from A. 

 malmgreni in that eyes are absent, not present; neuropodia have an 

 erect superior lobe from about segment 16 which is continued through 

 median segments; this lobe is absent from A. malmgreni (Theel). 



Holotype from station 1316-41, and paratypes in the Allan Hancock 

 Foundation. 



Type locality. — One mile southwest of Ben Weston Point, Santa 

 Catalina Island, California in 45 fms (station 1316-41). 



Distribution. — Southern California and Lower California, Mexico, 

 in depths of 20 to 172 fms, in mud. 



Aglaophamus rubella (Michaelsen), new combination 



Nephthys rubella Michaelsen, 1897, pp. 19-24, pi. 1, figs. 5-8; Fauvel, 

 1923, p. 373, fig. 145. 

 Interramal cirri are involute, thus this is referred to Aglaophamus. 



Aglaophamus rubella anops, new subspecies 



Nephthys malmgreni Berkeley, 1924, p. 290 (Fide Berkeley, 1945, p. 



327). 

 Nephthys rubella Berkeley, 1945, p. 327. 



Collections. — Mittelnacht Island, Canada (1, gift from Drs. E. and 

 C. Berkeley) ; off Alaska in 185-300 fms, dredged by U.S.S. Albatross 



(1). 



A complete specimen with 55 segments measures 17 mm long. The 



body is diffused reddish brown but there is no pigment pattern (pre- 

 served). The prostomium is pentagonal, with slightly arcuate frontal 

 margin and straight sides; the posterior margin is medially prolonged 

 so as to extend back to the end of the first segment. The frontal antennae 

 are at the anteroectal margins of the prostomium and nearly as large as 

 the posterior antennae; the latter are inserted at the sides of the pro- 

 stomium; there are no eyespots such as are present in the stem species.
