paratypes) and the Gulf of California, also were used in preparing 

 the description. This species was reported from 5 to 8 fathoms from 

 Lobos de Tierra Island by Regan (see reference above), which is the 

 only previous record from Peru. A small specimen from north of 

 Octavo Rocks, Colombia, and several from the Gal&,pagos Islands also 

 were examined. This species probably does not occur immediately 

 along the shore in very shallow water. One lot from Panama Bay (lat. 

 77°33'40" N., long. 79°43'20" W.) was taken at a depth of 153 

 fathoms. The largest specimen seen is 130 mm. long.
