CERADOCUS SHEARDI new species 



FkjL're 2 



Station 169, 12 specimens. 



These specimens do not agree with any of the known species of 

 Ccradocus as set forth in Keith Sheard's comprehensive paper "The 

 Genus Ccradocus." Records of the Australian Museum, vol. 6, Xo. 3, 

 1939. I am therefore describing the species as new and naming it 

 Ccradocus shear di in honor of Mr. Sheard.

 joint a little shorter than the second, lower margin bearing a distal

 tlagellum of about eight joints. Antenna 2, peduncle about equal in 

 length to that of antenna i ; Magelluin a little longer than the fifth 

 peduncular joint and consisting of about 16 joints. Mandibular palp

 Peraeopods 3 to 5 increasing consecutively in length. Peraeopod 3,
