Annelida of the Bermudas 629 



Head rather large for the body, evenly rounded in front and on 

 the sides, subtruncate posteriorly. Eyes are conspicuous; the 

 anterior ones are about twice as large as the others and farther apart, 

 the distance between being about equal to the diameter of a pos- 

 terior eye. 



Palpi large, broader than the head, united together nearly to the 

 tips, which are separated by a notch or emargination ; the length 

 of the projecting portion is equal to the length of the head. 



Tentacle is as long as the head and palpi combined, slender, some- 

 what fusiform proximally, the tip long and acuminate, without dis- 

 tinct annulations, but with some very minute rough points. Anten- 

 nae similar in form, but about \ shorter. Tentacular cirri two on 

 each side, of about the same length, and like the antennae in size 

 and form. First dorsal cirrus like the tentacular cirri, but about ^ 

 longer. The following cirri are about equal to the tentacle in 

 length, or nearly equal to the diameter of the body ; nearly smooth, 

 but showing a few scattered, minute, conical papillae when highly 

 magnified. The anterior parapodia are rather long, equal to about ^ 

 the breadth of the segment. 



The compound setae are long and rather numerous ; the upper 

 ones have a long, slendei-, nearly straight, acute blade, ratio about 

 1 : 8-12; the lower ones have shorter blades, ratio 1 : 5-6. In most 

 fascicles there is also a single, slender, needle-like seta, about as 

 long as the others. 



The oesophagus is short and rather stout, occupying about 3 seg- 

 ments, and in length about equal to the stomach, which is thick and 

 nearly cylindrical, occupying 2^ segments; it is covered with close 

 rows of dark clustered cells. 



Grubeosyllis rugulosa, sp. nov. 



A very small species with 28 segments, with the dorsal surface 

 of the body and cirri roughened with minute conical papilla?. 



Eyes well developed, dark brown, close together. Palpi large, 

 united nearly to the tips, longer than the head, a little broader than 

 long. Tentacle and antenna; of about the same form and size, 

 shorter than head, fusiform, with a small acuminate tip. Tentacular 

 cirri short, similar to the tentacle in size and form, nearly equal. 

 Dorsal cirri all short and mixch like the tentacular cirri. 



The compound setre are rather long and slender, usually 4-6 in a 

 fascicle; in the anterior fascicles the upper ones have rather long, 

 narrow, slightly curved blades, and the lower ones blades about 

 half as long and more incurved ; posteriorly they are all shorter and
