DE. BAIED ON THE APHRODITACEAN ANNELIDES. 181 



Family II. IPHIONIDiE. 

 (Ipliionea, Kinherg ; Polynose Iphionse, Savigny.) 



Facial tubercle small, placed between two antennse, wbicli are 

 produced from the surface of the face ; no tentacle ; palpi thick ; 

 tentacular and buccal cirri slender ; elytra reticulated. 



There is only one genus as yet belonging to this family, which 

 Kinberg, adopting the divisional denomination indicated by Sa- 

 vigny, has named Iphione. The typical species is the Polynoe 

 muricata of Savigny, so beautifully represented by that author in 

 his great work on Egypt. 



Grenus Iphione, Kinberg, I. c. p. 383. 



Polynoe Iphione, Savigny, Syst. Annelid. 



Eyes four, sessile ; cephalic lobe produced from between the basal 



joints of the antennse, which are longer than the lobe itself; elytra 



13 pairs. The setse of the dorsal branch of feet are fine subulate 



hairs : bristles of ventral branch placed close to them, and serrate. 



Sp. 1. Iphione mueicata. 



Polynoe muricata, Savigny, I. c. Atlas, tab. 3. figs. 1, Li., 1. ii. 



This is a well-marked species, and resembles at first sight a 

 species of Chiton, with which, as Savigny says, it is often con- 

 founded as it creeps slowly upon the stones under the water. It 

 is a native of the shores of the Eed Sea, as also of the coast of the 

 Isle of France (Mus. Brit,). 



Sp. 2. Iphione otata, Kinberg, I.e. and Fregatt. Kugen. Besa, 

 p. 8, tab. 3. figs. 8, 8 a-8 e. 

 I have not seen this species, but it appears quite distinct. 

 Kinberg says it is a native of the Pacific Ocean, having been 

 taken at Honolulu, one of the Sandwich Islands.

Family III. POLYNOID^. 



(Polynoina, Kinberg, Polynose simplices, Savigny.) 

 No facial tubercle ; tentaculum in general long ; two antennse ; 

 jaws large and horny ; eyes four in number ; elytra 10 (?) or 12 to 

 35 pairs ; segments of body not bearing elytra, furnished with a 

 dorsal cirrus ; no branchise. 



Genus I. Lepidonottjs, Leach (s. str. Kinberg).
