one according to size of the worm, and the number of setigerous 

 abdominal segments is either thirteen or fourteen. Many contain 

 nearly mature ova or sperm. 



Stations all in the vicinity of Point Pinos, Monterey Bay, 4461, 

 285-357, green mud; 4517, 750-766 fathoms, green mud and sand; 

 4528, 766-800 fathoms; 4536, 1006-1041 fathoms, hard sand and 

 mud; 4537, 861-1062 fathoms, hard sand and mud (18 specimens); 

 4538, 795-861 fathoms, hard gray sand and mud (80 specimens); 

 4546, 849 fathoms, fine black sand. 



Ampharete gracilis Malmgren. 



^ Several mud tubes contain fairly well preserved specimens of a 

 small slender species conforming closely with Malmgren 's des- 

 cription and figures. The paleoli are twelve to fourteen, colorless, 

 very slender and regularly tapered, forming small inconspicuous 

 fans scarcely reaching the end of the prostomium and not meeting 

 medially. 



Stations 4433, off Santa Rosa Island, 243-265 fathoms, green 

 mud; 4468, off Santa Cruz Lighthouse, 32-309 fathoms, fine sand; 

 4513, off Point Pinos Lighthouse, 389-456 fathoms, green mud. 



J Ampharete grubei Malmgren. 



The three specimens agree in having the prostomium trilobate 

 anteriorly and the paleoli fifteen or sixteen, forming rather compact 

 fans, regularly tapered to attenuate tips but much less slender than 

 those of A. gracilis. Pygidium a short ring bearing a circle of 

 eighteen short, slender cirri a])out as long as one-half the diameter of 

 the pygidium, except that two lateral pairs are twice that length. 



Station 4517, 750-766 fathoms, green mud and sand. 



Lysippe annectens sp. nov. Plate XVII, figs. 11-13. 



Cephalic end and particularly the broad fimbriated lip with 

 much of the aspect of a Samytha. Prostomial shield shorter and 

 broader than usual in that genus, nearly quadrate, the apex not 

 bifurcated and less prominent than in S. sexcirrata and without 

 upturned border. A pair of short prominent transverse series of 

 small eye-spots near the posterior border of cephalic shield. Lateral 

 lobes very small. Margin of lower lip fimbriate, crenulate and 

 furrowed. Tips only of numerous very short smooth tentacles 

 exposed. 



Branchial fold high and prominent, transverse, on I\' and V, 

 bearing four pairs of distinct scars in the usual pattern, the two 

 inner posterior nearly in contact, the outer posterior connected
