Alciopidce. 
Alciopina panceri, sp. n., Buchholz, I, c. p. 98, Taf. 4. figs. 1 to 4, found 
parasitic in Cydippe densa, Forsk., from the Bay of Naples, making with the 
A. parasitica, Olap. & Banc., and lihynchonerulla ?, Pane., the third form 
found living in the interior of this Ctenophore. 
Claparede and Panceri’s paper on an Alciopid, a parasite of Cydippe densa 
(see ‘ Zool. Record/ 1807, p. 635) will he found translated in Ann. & Mag. 
Nat. Hist. ser. 4, vol. iv. July 1869, pp. 29-34, pi. 6. . 
CHiETOPTERIDEA. 
Phyllochcetopterus arahicus, sp. n. (Ehrh.), Gruhe, /. c. p. 607, very near P. 
gracilis, Gr. 
The development of the following species is described by Claparede 
& Meeznikow, 1. c . : — 
Telepsavus costarum, p. 178. 
Phyllochcetopterus socialis ?, p. 181. 
Clymenea. 
Dasyhranchus carneus, sp. n. (Ehrb.), Grube, 1. c. p. 605, Tor ; queried by 
Grube as perhaps a var. of D. caduci, Gr. 
Leucodorea. 
The development of the following species is more or less fully 
described by Claparede and Meeznikow, 1. c . : — 
Spio fidiginosus, Clprd. p. 169. S. meeznikowianus, Clprd. p. 170 : this 
species differs from all hitherto known Chaetopods in the development of 
spermatophores, which are to be found regularly disposed in the segmental 
organs of the middle and lower, never in the upper portions of the bodies of 
the males ; this, it is well to note, is a fact in favour of the author’s view 
about the segmental organa. Several laiwai of unknown species are described 
at p. 176. 
Nerine cirratida {=.Lumhricus cirratulus, Delle Chiaje), p. 173. It is 
most remarkable that in the ova of this species the yelk should remain the 
same as when first formed in the ovary, as a wreath of transparent balls or 
bladders, whose significance is quite enigmatical. 
Polydora {Leucodore, Johnst.), species unknown, p. 175,
