354 DE. BAIKD ON SEVERAL GENERA OF EUNICEA. 



Family II. ONUPHIDID^. " 



Onuphididae, Malmgren, Annulat. Polychceta Spetsberg. Sfc, 1867. 



Head with lobes as in Eunicidae, furnished with seven organs 

 usually described as antennse or tentacula. Two spring from the 

 front of the head, and are very short (anfenmiles) . The remain- 

 ing five are as in Eunicidse. Tentacular cirri generally present, 

 sometimes wanting. Branchiae pectinated or plumose — or simple, 

 consisting of only one filament. Eyes two. Maxilla? as in 

 Eunicidae. 



To this family may be referred five genera, four of which have 

 already been described, which may be thus characterized : — 



I. Onuphis, Audouin ^ M.-Edwards. Branchiae pectinate. 

 Tentacular cirri placed laterally on buccal segment. Tentacle, 

 antennae, and palpi annulated more or less throughout their whole 

 length. 



II. DiOPATEA, Audouin ^ M.-Edwards. Branchiae plumose, 

 the branchlets disposed in a spiral tuft round a central stalk. 

 Tentacular cirri placed on the dorsal portion of the buccal seg- 

 ment. Tentacle, antennae, and palpi strongly annulated at the 

 inferior or basal portion only. 



III. Teadopia {gen. nov.). Branchiae pectinate. Tentacular 

 cirri placed on dorsal part of buccal segment. Tentacle, antennae, 

 and palpi strongly annulated on the lower or basal portion. 



IV. Notheia, Johnston {Ilalmgren). Branchiae bipartite only. 

 Tentacular cirri placed on the dorsal portion of buccal segment. 

 Tentacle, antennae, and palpi simple, not annulated on any por- 

 tion of their length. 



V. Htalincecia, Malmgren. Branchiae reduced to a simple 

 branchial filament. No tentacular cirri. Tentacle, antennae, and 

 palpi annulated at the inferior or basal portion. 



Genus I. Onuphis, Audouin <Sf M. -Edwards, Litt. de la France, 

 ii. 151, t. 3a. figs. 1-5 ; Malmgren. 



We have no specimens belonging to this genus in the British- 

 Museum collection. 



Genus II. Diopatea, Audouin 6f M.-Edivards, I. c. 155 ; Kinherg, 



Malmgren, Sfc. 



Branchiae plumose, not pectinate, but consisting of a tuft of 

 many short filaments rolled in a spiral form round a central stalk.
