ResumoA new species of chimaeroid egg capsule, Rhinochimaera caucasica, from strata in the North Caucasus tentatively identified as of Lower Cretaceous age, is described. A summary review of the 31 known occurrences of these reproductive bodies from all parts of the earth is presented and the difficulty in treating them taxonomically is discussed. Justification is made for reference of the more complete, specifically named specimens regardless of geologic age to either one or the other of the living genera Harriotta, Rhinochimaera, and Callorhynchus. — D.
