Description

Delectopecten gelatinosus (Mabille and Rochebrune, 1889)

 

 

Pseudamussium gelatinosum Mabille and Rochebrune, 1889: H.126, Powell, 1960: 176.

 

Pecten (Pseudamussium) gelatinosus: Dall, 1908: 403.

 

Propeamussium (Cyclopecten) gelatinosum: Carcelles, 1950: 76, pl. 4, fig. 73; Carcelles and Williamson, 1951: 330.

 

Palliolum gelatinosum: Soot-Ryen, 1959: 32, pl. 1, fig. 9.

 

 

MATERIAL EXAMINED: Eltanin Stns 291, 1605.

 

 

DISTRIBUTION: This species (if D. gelatinosus is a separate species) seems to be confined to a relatively small area off Southern Chile and Magellan Strait in 225-731 m.

 

 

REMARKS: Grau (1959: 47) included D. gelatinosus in the synonymy of D. vitreus Gmelin, 1791. Knudsen (1970: 179) queried whether all the forms included in D. vitreus by Grau and by Clarke (1962) should be included in this species. There seems little point in including this southern South American form in D. vitreus until a more critical analysis than that of Grau can be undertaken.”
