wliich is like that of the Newport specimen. The anterior foramen of the atlas is 

 incomplete, as in that specimen, and the spines of the conjoined vertebra? are 

 vertical and pointed. (PI. 25, fig. 1.) 



Fifth cervical: Spine wanting. Arch complete. Inferior lateral process un- 

 developed, or abraded. 



Sixth cervical: Spine and processes broken. Arch wide. 



Seventh cervical: Similar to that of tlie Newport skeleton, but the spine 

 obsolete or broken. 



TUOR.VCIC VERTEBRA. 



Barnegat City (female). — First thoracic: Spine vertical, pointed, about as high 

 as arch and centrum together. A moderately long process with articular facet 

 for tubercle of rib on side of neural arch; facet elliptical and directed a little down- 

 ward and forward. A smaller facet for head of second rib on posterior upper edge 

 of centrum. 



Seventh thoracic: Metapophyses long, extending horizontally, straight supe- 

 riorly. A small articular facet on the outer side near the base, directed dowoiward; 

 strongest on right side. A very small facet on posterior upper edge of centrum, 

 scarcely noticeable on right side. Neural spine rather narrow at tip; superior 

 margin straight. 



Eighth thoracic: Metapophyses squared and thin. A distinct transverse 

 process on side of centrum about half as broad as the centrum is long, and as long 

 as centrum is broad; flattened, squared, and a little curved backward and upward. 

 Articular facet for rib elliptical and directed oblicjuel^' backward. A broad, shallow 

 groove across base of transverse process, the anterior edge of which is emarginate 

 proximally. Neural spine as in seventli thoracic. 



Ninth thoracic: Metapophyses scjuared. Transverse process similar to that 

 of eighth thoracic, but equal to centrum in length, little narrowed at base, and 

 directed outward; anterior edge convex, posterior concave; articular facet occiqjy- 

 ing the posterior half of the distal edge. A very shallow groove proximally. 



Newport (male). — First thoracic: Neural spine a little curved backward and 

 rounded at tip; much higher than length of arch and centrum together. Articular 

 facets as in Barnegat skeleton. 



Seventh thoracic: Metapophyses similar in shape to those of Barnegat skeleton 

 but with a very distinct facet on side of arch, terminating a process about as long 

 as the greatest diameter of the facet; surface of facet rugose. Below this process, 

 on side of centrum, a very large, oval, sessile facet, reaching forward nearly to the 

 anterior face of the centrum and upward to its superior edge. A very low, small 

 swelling on the posterior superior edge of centrum, probably indicating the point 

 of attachment of a cartilage connecting the head of the eighth rib. Neural spine 

 expanded at free end, and superior margin rounded. 



Eighth thoracic: Metapophyses similar to those of Barnegat skeleton. A 

 distinct transverse process nearly as broad as the length of the centrum, oblong or 

 squared, flat, directed somewhat backward, but not upward. Articular facet for 

 rib not occupying whole of free end and only slightly directed backward; anterior 

 margin as in Barnegat skeleton. Neural spine similar to that of seventh thoracic.
