EUNICE FLOEIDANA. 439 



of G-orgonidse, fragments of Crustacea, and fragments of shelly tubes of Serpulids 

 ( Hydroides) . 



Habits. — 0. F. Miiller mentions the occurrence of this species in " Madreporae," and 

 more recently Marenzeller observes that this species, like E. floridana, Pourtales, inhabits 

 coral-stocks of Loplwlielia prolifera and Amphihelia oculata. Such appears to be the habit 

 of certain Eunicids in all seas, the worms, as Dr. Alcock tells us, for instance in the stocks 

 of Lophohelia investigator is in the Indian Ocean, living in " tunnels formed by a crust of 

 scleroderm that connected two neighbouring branches." 1 



Reproduction. — Those obtained in Norway by Canon Norman were loaded with ova 

 and sperms in July. 



In the c Encycl. Meth.' (1827) Leodice pinnata, Lamk., is shown with few divisions 

 to the branchiae, whilst Leodice norvegica (idem, Vers, i, p. 134, Plate LVI, figs. 5 — 7) 

 has a larger number of divisions in the branchiae (six or seven), and the dorsal cirrus is 

 larger. 



0. F. Miiller (1788) distinguished his N.pennata from N. pinnata by the presence of 

 whitish globules (ova ?) above and below the intestine, and by the pennate instead of 

 pinnate branchiae, which arise in the former on feet seven to forty, and in the latter from 

 feet five to twenty-six. Moreover, he figures the former with a dark speck at the base of 

 the dorsal cirrus, and a median line of dark specks along the dorsum. 



(Ersted considered that the branchiae of the male E. norvegica were less divided (from 

 three to five pinnae) than those of the female, which had eight pinnse on the branchiae, 

 and he thus made E. pinnata of 0. F. Miiller the male, and E. pennata the female of the 

 species. In this connection Grube 2 observes that a female example with ova showed 

 from seven to thirteen processes in the branchiae, whilst one with minute eggs had four 

 divisions. 



Dr. Johnston's description (1865) has been held as pertaining to this species, though 

 he states that he had not seen a specimen. The origin of the branchiae on the seventh 

 segment and the occurrence of from three to thirteen filaments in the branchiae are 

 differences. What the same author's E. antennata may be is uncertain. 



Tauber places Eunice fasciata under this species, but he gives no definite reasons. 

 In E. fasciata, however, the branchiae continue to the end of the body, whereas in E. 

 norvegica they cease at the fortieth foot. 



4. Eunice floridana, Pourtales, 1869. Plate LXV, figs. 7-7/; — head and teeth; Plate 

 LXXV, figs. 2 and 2 a— feet; Plate LXXXIII, figs. 10-10 b— bristles. 



Specific Characters. — Head with the palps grooved dorsally. Eyes behind the cirro- 

 phore of the frontal (external) tentacle and exterior to the lateral tentacles. Median 

 tentacle as long as first ten or eleven segments. Tentacles slightly annulated. No other 

 process is so. Tentacular cirri stretching beyond the palps. Body of 110 to 150 or more
