26 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 15 



Records of G. brunnea Treadwell (1914, p. 198) from Deadmans 

 Island near San Pedro, California, July 28, 1902, and from San Pedro, 

 June 22, 1895 and July, 1898, also go to G. littorea, as I was able to 

 confirm by examination of these collections, now deposited at the Allan 

 Hancock Foundation. 



G. littorea is an intertidal species, occurring in marine sloughs and 

 estuaries, especially along the shores of southern California, north to 

 Point Mugu. The substratum occupied is fine muddy sand at very low 

 water line. 



Holotype. — from station 1451-42 and paratypes, in the Allan Han- 

 cock Foundation. 



Distribution. — This is known only from southern California. 



Goniada quinquelabiata Augener 



Goniada emerita quinquelabiata Augener, 1906, p. 158. 

 Goniada congoensis quinquelabiata Augener, 1918, p. 397. 

 Goniada magna Treadwell, 1945, pp. 2-3, figs. 6-8. 



Material examined. — Type specimen of Goniada emerita quinquel- 

 abiata Augener, no. 2297 in the Museum of Comparative Zoology, 

 Cambridge, Massachusetts, and type specimen of Goniada magna Tread- 

 well, no. 3387 in the American Museum of Natural History, New 

 York. 



The type of Goniada emerita quinquelabiata is somewhat hardened 

 and much twisted but in satisfactory condition to identify its significant 

 characters. The length of the posteriorly incomplete specimen with 170 

 segments is about 130 mm. The prostomium agrees closely with that 

 described below, for Goniada magna Treadwell; there are no eyespots. 

 The basal ring has a pair of small foliaceous lobes at the sides, in line 

 with the parapodia farther back. 



The proboscis is only partly everted; the greater part is seen by 

 dissection to extend back so that the paragnathal ring is in segment 25. 

 The macrognaths are large, with 5 teeth each; micrognaths consist of 

 similar dorsal and ventral arcs, each with 24 dark pieces. Chevrons 

 number 19 pieces on one side and 15^ on the other. The proboscidial 

 organs are thickly strewn over the surface, closest and most numerous on 

 the dorsal side, diminishing in number so as to be sparest on the ventral 

 side. They are all of one kind ; each consists of a small mound covered 

 over by a chitinized sheath with a distal pore; on the abgnathal side of 

 the pore is a longer spur directed distad and on the gnathal side a 

 shorter spur directed obliquely upward; they resemble closely those 

 shown in plate 6, fig. 6.
