644 A. E. Verrill — Turbellaria, JVemertina, and 



Branchiae begin as simple cirri on the 3cl setigerous segment; they 

 have 2 cirri on the 6th ; 3 on the 8th ; 4 on a few segments farther 

 back. On the 46th, which is the last segment preserved, they have 

 two cirri. From dead corals ; only one example. 



The setre resemble those of L. hlnominata and L. stlgmatura. It 

 is allied to X. arttculata (Ehl.) and to L. ornata (Andrews). 



Leodice unifrons, sp. nov. 



A small slender species. Head undivided, rounded in front, with- 

 out any frontal emargination, the outlines nearly semicircular. Eyes 

 rather large, black. Antennae articulated, with the annuli unequal, 

 the distal ones elliptical, twice as long as wide, and very distinct ; 

 the median antenna is rather longer than the head and buccal seg- 

 ment ; the inner laterals are a little shorter ; the outer laterals about 

 half as long as the median. Tentacular cirri are obscurely annu- 

 lated, slender, about equal to the length of the buccal segment. 

 The dorsal cirri are long, equal to the longest branchial cirri. 



The branchiae begin as simple cirri on the 3d setigerous segment; 

 two branched ones appear at about the 8th segment ; the largest 

 are pectinate, with five or six long, slender, subequal cirri on the 

 16-23d ; trifid on the 34th; simple branchiae continue nearly or quite 

 to the posterior end of the imperfect specimen, which has 43 segments. 



In life the color is pale brown with a median dorsal row of white 

 spots, one to a segment, and with olive-brown irregular mottlings on 

 each side ; antennae pale, translucent, banded with flake- white. 



The only specimen found had lost the posterior segments. It was 

 about 1^™°' in diameter, in life, and 60-70'"'" long. 



Flatts Inlet, in shell-sand at low-tide. 



IJeodice margaritacea, sp. nov. 



A small long and very slender species, nearly white, with a pearly 

 iridescence. Antennae slender, distinctly annulated ; gills short 

 pectinate; anterior parapodia prominent; posterior ones small. 

 Head slightly bilobed ; eyes rather large. Antennae very slender, 

 rather long ; the median reaching back to the 2d or 3d setigerous 

 segment ; inner laterals a little shorter ; outer laterals about \ as 

 long as the inner. All are unusually slender, scarcely tapered, very 

 distinctly annulated distally, the joints being constricted and the 

 divisions longer than broad. Tentacular cirri slender, tapered, acute, 

 reaching about to the front edge of the buccal segment. The 1st 

 buccal segment and cirriferous ring together are about equal to the
