150 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL.14 



located on the outer side at the proximal end of the vibracular chamber ; 

 radicles smooth, with a few small barbs at the distal extremities. 



Ovicells 0.18 to 0.20 mm wide, broader than long, smooth, with a 

 few irregular surface lines and without pores. 



Hincks described the species from "Cumshewa Harbor," British Co- 

 lumbia. Robertson recorded it from Puget Sound to La Jolla, Cali- 

 fornia, more abundant northward, and O'Donoghue found it at numer- 

 ous localities in British Columbia. 



Hancock Station: Numerous stations from Oregon south to San 

 Diego, California. It is most abundant in shallow water but was dredged 

 at Station 1228-41, oE San Pedro, southern California, 126 to 138 fms. 

 The only record south of California is Station 557-36, off White Rock, 

 Isla Partida, Gulf of California, 28°55'30''N, 113°05'35"W, 45 fms. 



Scrupocellaria inarmata O'Donoghue, 1926 



Scrupocellaria inermis O'Donoghue, 1923:18, preoccupied by S. inermis 

 Norman, 1868, and changed to fnarwc/fl by O'Donoghue, 1926:41. 

 This species, described from Trincomali Channel, British Columbia, 

 is similar to S. varians Hincks, as indicated by O'Donoghue. The dif- 

 ferences as pointed out by O'Donoghue are as follows : 



Smaller than varians; absence of spines; absence of scutum; absence 

 of frontal avicularia on the lower zooecia of an internode, and the lateral 

 avicularia are all small. However, it agrees with varians in the characters 

 of the vibracula and ovicells and may be merely a well-marked variety of 

 that species. It has not appeared in the Hancock collections. 



Family Epistomiidae Gregory, 1903 



Genus SYNNOTUM Pieper, 1881 



Zooecia in pairs back to back, each pair connected by tubular pro- 

 longations with the second pair below it. There are sessile lateral avicu- 

 laria at the distal ends and frequently a stalked avicularium between the 

 two zooecia at or near the distal end. No ovicells, but slightly expanded 

 gonozooecia. Genotype, Loricaria aegyptiaca Audouin, 1826.
