Text-fig. 45. Amphicaryon ernesti sp.n. Three views of a larva from 'Discovery II' St. 1584, 100-50 m., x 29. 



Amphicaryon peltifera (Haeckel, 1888). 

 Mitrophyes peltifera Haeckel, 1888 a. 



A single specimen was taken at 'Discovery II' Station 1584 in an open haul from 100-0 m. 



All the radial canals of the larger nectophore are simple. There is no nectosac in the shield-shaped 

 second nectophore, but the characteristic three-branched canal which distinguishes it from A.acaule 

 and A. ernesti can be seen. 



As mentioned above, it has seemed best not to use Haeckel's slightly prior name Mitrophyes for 

 the genus since it has so long been out of use, but to attempt to have the well-known name Amphicaryon 

 placed on the list of nomina conservanda. 



Three other specimens of this little-known species which I have had for study are from : 



'Discovery II' Station 1580, 450-0 m., 2 ex. 

 'William Scoresby' Station 459, 135-0 m., 1 ex.
