of short filaments; posterior appendage non- 

 filamentous. 



Description. — Escal appendage pattern B (Pietsch 

 1974a, fig. GOB); esca with anterior appendage ap- 

 proximately as long as escal bulb, bearing three, 

 short branches at distal tip; distal end of internal, 

 pigmented tube of anterior appendage with a cir- 

 cular, translucent "eye-spot"; medial appendage 

 represented by a tuft of extremely short filaments; 

 terminal papilla bulbous, with a distal pigment 

 spot; posterior appendage nonfilamentous, con- 

 sisting of a large, compressed wedge of tissue on a 

 short, narrow base, bearing two or three, short 

 filaments on each side of anterior surface, and two 

 winglike projections, one above the other, on pos- 

 terior margin; anterolateral appendages absent 

 (Figure?). 



Suboperculum unusually long and narrow, 

 upper end tapering to a point without indentation 

 on posterior margin (Figure 8); length of lower 



fork of operculum 27.3% of SL; ratio of lengths of 

 upper and lower forks of operculum 0.56. 



Epibranchial teeth absent; teeth present on 

 pharyngobranchial II. 



Counts and measurements in Table 2. 



Etymology. — The name pterurus is derived from 

 the Greek pteron, meaning wing, and ura, tail, 

 alluding to the winglike posterior escal appendage 

 of this species.

Diagnosis. — A species of Oneirodes differing from 

 all previously described species in escal morphol- 

 ogy: anterior appendage noncylindrical, com- 

 pressed, without pigmented, internal tube; medial 

 appendage present; posterior appendage cylindri- 

 cal, unbranched. 



Description. — Escal appendage pattern B (Pietsch 

 1974a, fig. 60B); esca with anterior appendage 

 noncylindrical, strongly compressed and rounded, 

 darkly pigmented along distal margin in some 

 specimens; a pair of filamentous medial append- 

 ages; terminal papilla usually with two distal 

 pigment spots situated on midline, one just behind 

 the other; posterior appendage short, stout, and 

 cylindrical; anterolateral appendages absent 

 (Figure 9; Pietsch 1974a, fig. 116B). 



Suboperculum short, upper end tapering to a
