However, several specimens (UF 3984, IBUNAM-P9865, USNM 222431) have been collected from the southern GOM and a single individual (FMNH 90092) was collected from the continental slope off Honduras. In the northern GOM, this species occurs on the continental slope from the Texas/ Mexicoborder to off northwestern Florida at depths ranging from 300 to 510 m.  First Record in   GOM.The description of this species ( Bigelow and Schroeder, 1951b) was based on two specimens ( holotype USNM 152546, Figure 13, and paratype MCZ37160)both collected in the same general area, on the continental slope off the mouth of the MississippiRiver, in 1950.   Remarks.This is a deep water species that is rarely captured and, therefore, little is known of their biology.  Conservation Status.Data Deficient (as  Anacanthobatis folirostris) GOM, MCZ 15 296 USNM 152546 2 holotype
