156 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 22 



having the characteristic paleae, with a distal mucron. The species is 

 more widely known from the northeast Pacific Ocean in shallower ocean 

 bottoms (Berkeley and Berkeley, 1952, p. 69). 



Genus ANOBOTHRUS Levinsen, 1883 

 Anobothrus gracilis (Malmgren) 1866 

 Berkeley and Berkeley, 1952, p. 67, fig. 137. 



Numerous collections were taken in San Pedro, Santa Catalina, 

 Santa Cruz and questionably Tanner Basins. Most are smaller than 

 those taken from shelf depths, measuring usually less than 10 mm long. 

 An ovigerous one measures 8.5 mm long and 0.7 mm wide and consists 

 of 15 thoracic, and 12 abdominal setigerous segments. Paleae are well 

 developed and number 12 to 15 on a side. The 4 pairs of long, slender 

 branchiae are inserted in a single transverse row. The prostomium has a 

 pair of dark areas at the sides, and a pair of minute eyespots farther back. 

 Narrow, ventral gland shields are present through thoracic segments to 

 the third from last one. The tubes are thick, mud walled, and closely 

 adhere to the occupant. 



Anobothrus gracilis is cosmopolitan in occurrence, usually in moder- 

 ate depths (Berkeley and Berkeley, 1952, p. 67). 



Genus LYSIPPE Malmgren, 1866 



Lysippe annectens Moore, 1923 

 Moore, 1923, pp. 201-202, pi. 17, figs. 11-13. 



Individuals were taken in Santa Catalina, San Nicolas, Tanner and 

 questionably Velero Basins. They are smaller than those first described. 

 An ovigerous one from Santa Catalina Basin measures about 14 mm 

 long; the body consists of 17 thoracic and 10 abdominal setigerous seg- 

 ments. The branchial fold is high and prominent and carries 4 pairs of 

 cirriform branchiae. The lower lip is broad and deeply crenulated, with 

 14 or 15 lobes. Paleae are weakly developed, no larger than the setae of 

 the first setigerous segment. Ventral gland plates are present through the 

 tenth setigerous segment. 



Lysippe annectens is known from shallow to basin depths in southern 

 California.
