Part I.—EvupHrosynip&, AMPHINOMID®, APHRODITID®, PoLynoipH, ACo#TID A, 
and SIGALIONID&. 
THE materials from which the following observations have been made were kindly 
placed in my hands by the distinguished naturalists who superintended the dredging- 
operations in these expeditions, viz. Dr. Carpenter, Dr. Gwyn Jeffreys, and Prof. 
Wyville Thomson. I have, in the first place, to record my obligations to these gentle- 
men for their great courtesy. 
EUPHROSYNIDZ. 
Of the Euphrosynide a minute example (Huphrosyne lanceolata, nu. s.), about one 
tenth of an inch in length was dredged in 173 fathoms in sandy mud and corals off 
Treland in 1869. It is at once distinguished from the common JZ. foliosa by the shape 
of the branchiz, which for the most part are divided dichotomously, and terminate in 
lanceolate processes (Pl. LX XI. fig. 1). Asin allied forms, the inferior bristles are simple ; 
the dorsal are almost all injured in the single example, only one or two with the curved 
and serrated fork being visible. From £. borealis, GZrst., another British species, it is 
likewise separated by the form of the branchie and the structure of the bristles. The 
late Prof. M. Sars describes' the branchie of his E. armadillo as having the apices 
“conico-acuminatis,” else I should have been inclined to unite the present form there- 
with. 
AMPHINOMIDZ. 
Cuoita FucATA, De Quatref.?, occurred in considerable abundance in the collection 
made by Dr. Carpenter in 1870 ; viz. in 40 fathoms off Algiers, 60-100 fathoms east of 
Cape de Gatte (six miles from shore), 45 fathoms eight miles N.W. of Cape Sagres, 92 
fathoms in sandy mud on Adventure Bank, 128 fathoms off Tangiers, and 227 fathoms 
off Cadiz—the bottom temperatures in the two latter being 55°. The species seems to 
be most closely connected with the C. fucata of M. de Quatrefages? from Mascate. It 
differs, however, in the presence of four very distinct eyes—a larger pair in front on 
each side, and a smaller pair behind.
