Page 71, ZIPHIUS SOWERBIENSIS, add 



. Cast of skull. Presented by Dr. Acland. 

 Cast from Mr. Sowerby's specimen in the Anatomical Museum, 

 Oxford. 



Page 126, DELPHINUS MICROPS, add 



b. Skull, larger ; the skull behind the frontal longer, slightly 

 compressed; teeth ff on each side; length, entire, 18"; tooth- 

 line 10J, beak 12, lower jaw 15J; width at orbit 6J, at notch 3, 

 middle of beak If. 



This skull chiefly differs from the type skull of D. microps in 

 the back of the skull being much less convex, and in its being of 

 a rather larger size : can this depend on the sex of the specimen?
