from that genus, and would apparently refer it to tlie genus 

 Hermadion. It differs from that genus, however, in the number 

 of the elytra, whilst, on the other hand, the existence of two 

 distinct kinds of bristles in the fascicle of the dorsal branch of the 

 feet distinguishes it from all of the genera established by Kinberg. 

 I have therefore been obliged to propose for its reception a new 

 genus, which I have characterized as above. 



For the specimen of this species in the collection we are in- 

 debted to Mr. Jukes, who collected it during the voyage of H.M. 

 ship the ' Ply.' Unfortunately the habitat has not been preserved ; 

 but probably it is a native of the seas of Australia or New Zea- 

 land {Mus. Brit.). 



Grenus VII. Norepea, gen. nov. 



Head three-lobed. Tentacle attached to the margin of the 

 centre lobe ; palpi attached to the side lobes ; no antennae. Ely- 

 tra 14 pairs, covering the back entirely. Body short. 



Sp. Norepea Peronea.

This species approaches in general form and appearance to the 

 Folynoe {Iphione) muricata of Savigny. It differs, however, from 

 that species in the number of elytra, in having a tentacle, which 

 is wanting in the genus IpJiione, and in the absence of antenna?, 

 which, again, are present in Ipliione. 



I only know the animal in question from Schmarda's figure 

 and description. 



Grenus VIII. Heemenia, OriCbe, Annulata Oerstediana, p. 18. 



Tentacle long. Antennae only half the length of the tentacle, 

 but much exceeding the 1st elytron. No palpi. Elytra 12 pairs, 

 exceedingly small, except 1st pair. Branches of feet connate. 

 Body short. 



In his description of this genus, Grrube makes no mention of 

 the situation of tentacle and antennae, or appearance of cephalic 

 lobe; and the species upon which the genua is founded I have, 

 never seen.
