Lora equatorialis Dall, 1919: 44 , pl. 13 fig. 2.

? Leucosyrinx equatorialis – McLean 1971a: 120, fig. 38.

Type material

Syntypes

PACIFIC OCEAN • 3 specs; coast of Ecuador to Patagonia ; depth 122–407 ftm; USNM 97092 , 97070 , 697384 .

Remarks

The small shell (13.5 mm in shell length, according to the original description) is characterized by a very short siphonal canal, strong axial ribs extending from the subsutural ramp to the siphonal canal, and an extremely shallow, barely discernible anal sinus. These features exclude the species from Leucosyrinx . McLean (1971a: fig. 38) illustrated the radula of a specimen from the type series (USNM 97070), but due to the small size of the photograph, little can be discerned beyond the presence of duplex marginal teeth. This suggests that the species likely belongs to the family Pseudomelatomidae , though we are currently unable to determine its exact generic position.

Distribution

Type locality.
