336 PROCEEDINGS OF THE ACADEMY OF [Juiie, 



Proboscis — see above. Color slightly yellowish ; opaque from pres- 

 ence of sperm-balls with which coelom is packed. 

 . Type only, from.station 4.395, off Santa Catalina Islands, March 31, 

 2,045 fathoms, blue-gray mud. 



Sphaerodorum sphaerulifer sp. nov. 



Fragment of caudal end of a species related to S. cJaparedii Greeff, 

 but with the large spherical bodies more numerous. It is dark brown 

 and very opaque. Each segment bears on the dorsum two or three 

 pairs of large, and alternating with them smaller, spheroidal bodies, 

 all partially united at their bases into a somewhat irregular trans- 

 verse ridge. The smaller numbers are at the posterior end, and they 

 increase regularly as far as the piece extends to the middle segments. 

 Several similar but smaller bodies occur on the venter. Neuropodia 

 generally similar to those of S. brevicapitis, but the very extensile 

 neurocirri and postacicular lobes are much larger, a papilla appears 

 to be absent from the notopodial organ and the first (a smaller one) 

 of the transverse series of dorsal appendages may be the notocirrus 

 of each segment. Setae compound, similar to those of S. brevicapitis, 

 but with the joint more distinct and the appendage somewhat longer. 



The single specimen, included among some invertebrates presented 

 to the Academy by Professor Harold Heath, was taken from a deep- 

 sea fish-line in ^Monterey Ba}^ on July 16, 1902. 



HESIONID^. 

 Podarke pugettensis Johnson. 



About a dozen specimens with up to fifty-eight segments and except 

 for the eyes devoid of pigment. One is regenerating the caudal end. 

 Many have the proboscis, which has not been described, protruded. 

 It measures about 1.5 mm. long and half as wide, the basal two- thirds 

 swollen, bulbous and smooth, the distal portion subcylindrical or trun- 

 cated conical and more or less compressed; terminal orifice a vertical 

 slit surrounded by eight or ten faintly marked small papillae. 



The first mention of this species in literature is under the name of 

 Ophiodromus by Harrington and Griffin as a parasite on Asterias 

 in Puget Sound. 



San Diego Bay, Beacon No. 3 Shoal, March 1, 1904. 



PHYLLODOCID^ 

 Phyllodoce mucosa 0erste<L 



This species, already recorded from the North Pacific, appears to be 

 common off southern California. Most of the specimens are well
