148 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 22 



was based on specimens from Monterey Bay in 75 to 766 fms. The species 

 is more widely recorded from western Canada, in shallow to deep water 

 (Berkeley and Berkeley, 1952, p. 53). 



Genus MALDANE Grube, 1860 

 Maldanesarsi Malmgren, 1865 

 Moore, 1923, p. 237. 



Characteristic pigmented individuals are abundant in shallow bottoms 

 of southern California, in depths of 30 to 100 or more fms. Similar, 

 though pale or unpigmented specimens occur in San Pedro and Tanner 

 Basins. Like the shelf form, they occur in tubes of thick mud, closely 

 adherent to the occupant. The species has a cosmopolitan distribution in 

 shallow to eurybathic depths. 



Maldane cristata Tread well, 1923 



Maldane carinata Moore, 1923, pp. 233-235. 

 Hartman, 1956, pp. 295-296. 



This species was taken in San Pedro, Santa Catalina and San 

 Clemente Basins. As M. carinata it came originally from San Clemente 

 Island in 654-704 fms. 



The cephalic plaque is elliptical in outline ; its limbate margin is 

 divided by a pair of deep, smooth incisions into a pair of lateral flaring 

 lobes and a posterior lobe with smooth margin. A collar arises from the 

 posterior border of the peristomium; it is high, stiff and erect; its margin 

 is smooth except for a wide, shallow emargination middorsally. The 

 cephalic plaque has a prominent, arched carina beginning at the prostomial 

 palpode. The first 3 setigerous segments are strongly biannulate, with the 

 anterior ring glandular all around and the posterior parapodial one about 

 twice as long. Segment 6 has an anterior dorsal flange slightly overlapping 

 segment 5. The pygidium is a near duplicate of the cephalic plaque except 

 that it lacks a palpode and nuchal organs. 



Maldane cristata is known from western Mexico and California in 

 considerable depths. 



Maldane ?glebifex Grube, 1860 

 Berkeley and Berkeley, 1952, p. 45, figs. 85, 86. 



A single specimen from San Diego trough differs from other species 

 of the genus taken in the basins in that the anal flange is denticulate.
