Syn. Heteromysis spinosus Holmes, 1900

Material examined. Exuma Islands, Bahamas: Angel ®sh Blue Hole , Stocking Island ; 18 July 1998; three females (3.1±3.3 mm) collected with suction bottle approximately 360 m inside the cave at a depth of 29 m . South Andros Island, Bahamas: South Bight #2 Blue Hole, 4 October 1999; three females (3.0 ± 3.5 mm), two males (3.0, 3.2 mm) and three juveniles collected with plankton net and suction bottle from surface of silty sediments in 40 m depths. Exley’ s Boiling Hole ; 5 October 1999; three females (3.6±3.8 mm) collected with plankton net and suction bottle from water column and surface of silty sediment in 60±70 m depths.

Remarks. This stygophilic species was described by Walker (1898) based on material from Puget Sound. Successively, Holmes (1900) described a very similar species, Heteromysis spinosus , from California; W. M. Tattersall (1951) describing material from West Coast of Panama synonymized the latter with H. odontops , pointing out as well some negligible diOEerences between the two taxa. Later, O. S. Tattersall (1967) transferred H. odontops described by W. M. Tattersall from Panama to a new species, H. panamensis .

Our material from Bahamas is very close to the species odontops Walker, 1898 and Tattersall (1951), diOEering only by minor characteristics, which could well ®t the wide variability of this species. The lack of su cient number of specimens, especially males, causes us to ascribe provisionally our material to H. odontops .
