In speaking of the vibratile cilia of the perivisceral cavity of this species 
Claparede, in a footnote, says (p. 92), ‘^M. Williams a decrit et figure deja les 
cils vibratiles de I’intiSrieur de la branchie . . . Bien souvent encore, dans le 
cours de ce m^moire, j’aurai a relever d’excellentes observations dues a M. 
Williams Je suis le premier a reconnaitre que les recherches de M. 
Williams sont mal dig^rtles, qu’elles fourmillent d’errem*s resultant en grande 
partie d’une culture sp^ciale msuffisante 5 mais je ne pense pas qu’il faille 
m^priser un m»5tal pr^cieux parce qu’il est enferm^ dans uno gangue de 
moindre valeur.” 
Sthenelais fidiginosn, sp. n., Claparede, 1 . c. p. 94, pi. 4. fig. 2 j S. letolepis, 
sp. n., Claparede, /. c. p. 96, pi. 4. fig. 3, & pi. 6. fig. 1. This latter species 
resembles somewhat closely S. limicola (Ehl.) ; the most easily marked dis- 
tinction is that S. leiolepis has constantly four eyes, while S. limicola has but 
two. — S. dendrolepiSf sp. nov., Claparede, 1. c. p. 99, pi. 4. fig. 4, & pi. 6. fig. 1. 
Pholo'e synophthalmica, sp. n., Claparede, 1 . c. p. 79, pi. 3. fig. 1. The only 
individual observed presented the peculiarity, perhaps unique among the 
Aphrodites, of having elytra on the buccal segment. 
Eunicea. 
Ehlers would characterize this family as follows (/. c. 
p. 280) 
A. Jhe interposing pieces forming the upper jaw heterogeneous ; the pieces fol- 
lowing on the Trdgerf the untoothed pincei's {Zange')^ and the tooth become 
surrounded by a half circle of smaller pieces. The pinnae single j with several 
hmdles of seta (Eunicea labidognatha). 
I. The two halves of the upper jaws having an unequal number of pieces 
— one more in the left than in the right half. Cephalic segment with 
tentacles (E. 1. tentacidata'). 
1. Five posterior and two anterior long tentacles.
