 In the absence of a complete account of E. schizo- 

 branchia Clp., this species (including E. 

 leucodon Ehl. as a variety, see below) is the 

 onlj' member of the division. 

 E. Of generalised structure but gills absent.

Eunice aphroditois Mcintosh, 'Challenger,' xii. p. 282; Gravier, 

 Nouv. Arch, du Miis. Paris, 1900, p. 224. 



A single specimen, the posterior end of which is in process of 

 regeneration, from Goidu Reef, Maldives. The body is of very 

 nearly the same width throughout, viz. 2 cm. inclusive of parapodia 

 and setfe. 



It should be noted that in spite of the large number of their 

 branches the gills are quite small, not coveiing any appreciable 

 part of the dorsal surface of the body. The articulated piece of 

 the compound setae has been nearly always lost, but when present 

 it bears two hooks, and, like the acicular seta, corresponds exactly 

 with Mcintosh's figures from the Australian specimen obtained 

 by the ' Challenger.' The dorsal bundle of setse corresponds with 

 Gravier's account in the disproportionately small number and 

 the long slender points of the capillary setae, and in the number, 

 chai-acteristic shape, and granular surface of the combs. Since 

 these two points were not given by Mcintosh, and small variations 

 of the jaw-plates are not of systematic importance, the only 

 certain foundation for Gravier's var. djihoutiensis is the third 

 very small tooth found between the longer two of the articulated 

 pieces of the compound and acicular setse. This difference is 

 hardly sufficient to warrant the addition of a third name, especially 

 in view of the variation in the shape of these teeth noted in the 

 ' Challenger ' specimens.
