162 THE ANNELIDA POLYCHAETA. 



along both notopodium and neuropodium to the base. The margin may be 

 indented crenately, with the lobes large and few. No glands were detected in 

 the neuropodial fins of the first and second parapodia; but in the succeeding 

 pairs glands in the neuropodial fins are large, thick, and conspicuous. No 

 rosette in the trunk of the first parapodia. The fins of the caudal parapodia 

 are narrow and form a narrow fringe along the side of the notopodium and neu- 

 ropodium, and in the last ones is almost absent. The neuropodial and notopodial 

 branches of the tail parapodia are long in proportion to the proximal portion. 

 (Plate 27, fig. 6). 



Ovaries occurring in notopodia only, sometimes extending proximad into 

 trunk of parapodia. (Plate 27, fig. 5). 



Total length about 14.5 mm. Length of body, exclusive of the caudal divi- 

 sion, about 9.5 mm., the tail, the tip of which is missing, being thus 5 + mm. long. 



Locality. Galapagos near Hood Island: Sta. 4644. Surface. 7 Novem- 

 ber, 1904. One specimen. 



At once distinguished from the preceding in bearing well developed though 

 smaller parapodia along the tail and in lacking rosettes in the trunk of the first 

 parapodia, and especially in lacking the first tentacular cirri. 



ToMOPTERis, sp. a. 



Taken with the type of T. eura, sp. nov., is an immature TomopterisS mm. 

 long. It has thirteen pairs of parapodia, with the rudiments of a fourteenth 

 pair. There is indication of the beginning of the tail, but the appendage is very 

 short. The second cirri are longer than the body as in T. innatans, to which 

 species it may belong. There are no first cirri. 



Locality. Off Peru: Sta. 4659 (lat. 8° 51' S., long. 86° 05' W.). Surface. 

 14 November, 1904. 



ToMOPTERis, sp. b. 



A small specimen about 3.5 mm. long, in which there is but a short tail. 

 Fourteen pairs of parapodia are developed on the body and one pair at the base 

 of the short tail, which extends but slightly beyond them. The second cirri 

 are much longer than the body. The specimen is not definitely identifiable in 

 the present state of our knowledge. 



Locality. Off Lower Cahfornia: Sta. 4583 (lat. 22° 45' N., long. 110° 

 5' W.). 300 fms. to surface. Surface temp. 83° F. 11 October, 1904.
