POLYCHAETOUS ANNELIDS FROM PHILIPPINE SEAS. 597 



The parapodial modifications begin on somite 15. In a modified 

 parapodium the neuropodium has a dorsal, and the notopodium a 

 ventral sagittal lobe, which overlap, the notopodial being anterior. 

 Dorsal to the slender dorsal cirrus is a broad rounded lobe with 

 ventral to it, a lanceolate one extending to nearly the end of the 

 cirrus. The ventral cirrus is much like the dorsal in form, but rela- 

 tively a little heavier. Ventrally it carries a plate shaped like that 

 of the dorsal but larger. Dorsally, attached to its base, this cirrus 

 carries a zigzag three-pronged outgrowth, while on the ventral sur- 

 face of the neuropodium is another outgrowth very similar to this 

 but with four prongs. The setae are of the usual type with broad 

 terminal joint toothed along one edge. 



Most individuals show traces of brown spots on the dorsal sur- 

 face. When best developed these appear in the anterior unmodified 

 portion as prominent spots on the parapodia from the eighth to the 

 fifteenth. In the modified portion there is a median dorsal and two 

 lateral brown spots in each somite, with a double row of smaller 

 brown spots on the dorsal surface of each parapodium. Ventrally 

 these markings are most prominent in the modified region, where 

 the median row breaks up into a double row of smaller spots and the 

 parapodial row tend to coalesce into a single one. 



In the collections were a number of females in the epitokous condi- 

 tion, but none which resembled the above-described males sufficiently 

 to justify one in identifying them as of this species. 



Collected from Subic Bay ; Santa Cruz Harbor, Marinduque ; San 

 Miguel arbor, Ticao Island, a large number of individuals being 

 from the latter locality ; Port Matalvi, Luzon, and Eomblon. 



Type.— Cat. No. 18939, U.S.N.M., from latter locality.
