5. PHTSALTJS. 165 



One edge is smootli and rounded, but furrowed by a deep linear 

 groove ; the other is irregularly tuberoulated and spiculated. This 

 form is quite diiFerent from that of the pelvic bones of the specimen 

 in the Alexandra Park, vrhere they are each 18|" long, gently curved, 

 flattened, quite smooth along the edges, and mtii a prominent angular 

 projection from near the middle of the convex border. 



" The scapula is 31" in height and 51" in breadth ; the acromion 

 is 12" long ; the coracoid 5^". The humerus 19" long, 9" in greatest 

 diameter, and 26J" in girth at the middle. The radius is 32" long, 

 7^" in breadth at the upper and 9" at the lower end. The ulna 

 36" in extreme length, from the end of the olecranon, 30" from the 

 middle of its surface for articulating with the humerus, 10" in breadth 

 above and 6^" below. There are six ossifications in each carpus. 

 The phalanges appear complete. It should be stated that the latter 

 are not very exact, as the ends of the bones are more or less con- 

 cealed by the composition, which replaces the cartUage. The baleen 

 is present in both sides. The largest plates measure about 28" in 

 length. 



" The recent discovery of a large number of fossil remains of Ceta- 

 ceans in the excavations occasioned by the fortification of the city of 

 Antwerp has given a great impulse to the study of the osteology of 

 the existing members of the order in Belgium, and, chiefly by the 

 exertions of Professor Yan Beneden of Louvain, a very fine collection 

 has been brought together, in great part obtained from the Northern 

 seas, through the cooperation of the late Professor Eschricht of 

 Copenhagen. Many of the specimens enrich the admirable anato- 

 mical collection of the University of Louvain ; but most of the larger 

 ones have passed from the hands of Van Beneden to the Eoyal 

 Museum of Natural History at Brussels, where they are arranged 

 and displayed to great advantage, under the able direction of M. Du 

 Bus."— Flower, P. Z. S. 1864, 414-416. 



" In December 1841 a male Pin-Whale about 40 feet long was 

 stranded at Katwijk-aan-Zee, about six miles from Leyden. Dr. 

 Schlegel gave a figure and description of its external characters, 

 with some notes on its anatomy, in the second part of his 'Ab- 

 handlungen.' The skeleton passed into the hands of a person at 

 Scheveningen, at which place it was for some time exhibited. It 

 has been transferred to the Leyden Museum. 



" The skeleton was evidently that of a very young individual of the 

 genus Fhysaliis, agreeing in every particular, as far as I oovld ascer- 

 tain, with P. antiquorum. The bones were spongy, and the epi- 

 physes on the limb-bones and vertebrae all non-united, even that on 

 the hinder surface of the axis. The skull was about 9 feet long ; the 

 nasals were deeply excavated ; the orbital process of the frontals 

 narrowed at the extremity. The lower jaw^had a considerable curve 

 and a long coronoid process. As mentioned by Schlegel, the verte- 

 bral formula was C. 7, D. 15, L. 14, C. 24=60. The form of the 

 atlas and of the bodies of the cervical vertebrae were as in Physalus 

 generally ; the transverse processes were not developed, being in fact 

 mere stumps. The upper and lower processes were not united even
