142 ON A SKELETON OF A WHALE IN THE 



ends of the contrnm aro nearly tint, the po^^terior sli<^htly 

 concave. 



The follow! ;ii;- vertebra' are probably n.earer the end of the 

 series, as it appears that between first and second, in the hi^nre, 

 three or fonr bones are wanting-. 



As the figures show, in the second vertebra, the neural arch 

 is quite destroyed, but the left transverse process is in A'ery good 

 condition. The centrum is much heavier than in the first. Its 

 dimensions are: — length 72mm. (2 15-1(! inches), width 

 65min. (2^ inches), height GOmm. (2 5-16 inches), neural 

 canal 70mm. (2^ inches) wide. 



The transverse process is stout, much thickened at the end,, 

 flat above, convex below. It is nearly ])erfec't, and is 7<hnm. 

 (3 inches) long, 32mm. (l^ inches) wide next the centrum, 

 and 51mm. (2 inches) wide and 25mnL (1 inch) thick at the 

 end. This bone is shown in ])late IV, upv)er figTire. In the 

 third bone, which is ])i'ol)al)ly the eighth or ninth dorsal, w^e 

 have ])erha])s the most coni})lete of the series. The neural arch 

 and transverse ])roces.-es are fairly complete, as the figures show. 

 The centi'um of ihis vertel)ra is 01mm. (2i^ inches) high, 70mm. 

 (2f inches) wide, and 7() mm. ( ;] inches) long; the neural 

 canal is 37mm. high, and 57mm. wide. The left transverse 

 process, which is mo-t com])lefe, is 02 nun. long. The last dorsal 

 in the s])ecimen, fourth of 1st series of plate IT, is ]KU'ha])s the 

 eleventh. The centrum, especially beneath, has the characters 

 of the hnnbars. It is 05mm. (2-| inches) high, 70mm. (24 

 inches) wide, and 82mm. (3| inches) long. The left transverse 

 process is (piite cf»m])lete, and shows all the features of that ])art 

 of the bone. It is 121nim. ( 4;| inches) long. 



Lumbar vertebrae. — In the absence of chevrons it is difficult 

 to determine the point where the lumbars pass into the cavidals, 

 but five of the bones are considered a& lumbar. The bodies 

 lengthen and the vertical dianu'ter increases towards the caudal
