Description: The mantle is muscular except for 

 the thin-walled posterior end (tail) consisting of a 

 gelatinous alveolar material. The mantle is 

 widest (MWI 29.1 -.52. 4-34.1) at the anterior edge 

 and tapers into a blunt end. The anterior ventral 

 margin is slightly excavated forming low, 

 pointed lateral angles on each side. The dorsal 

 margin is extended anteriorly into a median 

 rounded lobe. 



The fins are wider (FWI 62A-69.5-73.2) than 

 their lengths (FLI 52.0-59.0-64.0). They are 

 attached anteriorly at about the midpoint of the 

 mantle length. The anterior margin of each fin 

 forms a rounded lobe. The lateral angles (72°) of 

 the fins are rounded. The posterior margins are 

 straight and are fused to the mantle separately, 

 except for a point (difficult to see) near the tip of 

 the mantle where they join. 



The funnel is large, triangular, and has a 

 broad base. The funnel-mantle locking cartilage 

 is straight, the ends are rounded but the anterior 

 end is slightly narrower; the median groove is 

 shallow. The funnel organ of the holotype is large 

 (9 mm long). The dorsal pad has an inverted V- 

 shape with a slender papilla anteriorly and with 

 prominent ridges on the limbs; each limb is 

 about 2.5 mm wide. The ventral pads are oval 

 and elongated (7 mm long, 3 mm wide). 



The head is nearly square in cross section and 

 narrower than the mantle (HWI 21.8-26.0-29.3). 

 The funnel groove has a distinct edge on each 

 side. The edges continue posteriorly to form the 

 first pair of nuchal folds which bears the small 

 olfactory papillae. The second and third nuchal 

 folds are crescentlike membranes on each side
