On the seventh thwacic the facet for the tubercle of the rib, instead of being 

 very prominent, becomes inconspicuous. The metapophysis is flat and squared, 

 and there is no lower facet on tlie side of the centrum. On the eightli thoracic the 

 metapophysis is thin, squared, and vertical, and a well-formed transverse process 

 appears oii the side of the centrum. The transverse processes of the ninth thoracic 

 are a little curved backward, and on the first lumbar and succeedins vertebra? bent 

 forward. These processes are less tapering on all the lumbars than in the Newport 

 skeleton. They disappear on the eighth caudal. None is perforated. 



The longest neural spine is on the sixth lumbar, and on all the lumbars both 

 the anterior and posterior edges are somewhat convex. Hence their shajje is rather 

 different from those of the Newport skeleton, in which tiie anterior margins are 

 somewhat concave. The tips of the spines are rather suddenly expanded. The 

 spines of the caudals are rather more expanded at the tip and more inclined back- 

 ward than in the Newport skeleton. They disappear on the eleventh caudal. 



The horizontal plate joining the metapophyses is noticeable on tlie fifth caudal. 

 The ridge on the side of the neural arch is first noticeable on the fourth caudal and 

 is very strong on the fifth, sixth, and seventh. The metapophyses are last traceable 

 on the twelfth caudal. 



GJiarlefiton (female, jr.). — This skeleton resembles the Newport one as regards 

 the facets for the articulation of the tubercles of the ribs, except that the seventh 

 thoracic resembles the sixth and has no lower facet on the side of the centrum. The 

 transverse processes of the ninth thoracic are rather strongly curved backward, 

 while those on the last thoracic and first lumbar are nearly straight. On succeed- 

 ing vertebra they are inclined forward. They are last traceable on the eighth or 

 ninth caudal (vertebra 35 or 36). None is perforated by a foramen. 



Though the vertebra are defective, there appear to have been no neural spines 

 on the fourth to the seventh cervicals, inclusive. The spine on the first thoracic is 

 short, and on the first to the fourth is pointed. The spine disappears on the tenth 

 caudal (vertebra 37). 



The metapophyses assume the vertical position on the eighth thoracic. The 

 last of these processes is barely traceable on the tenth caudal (vertebra 37). The 

 rido-e on the side of the neural arch is well marked on the fifth to the ninth caudals, 

 inclusive. On the seventh caudal (vertebra 34) the anterior and posterior facets 

 for the chevrons are united on the right side, and on the eighth caudal and suc- 

 ceeding vcrtebrip on both sides. 



CERVICAL VERTEBR.E. 



Barnegat City (female).— The first four cervicals are united. The foramen 

 above the anterior articular facets of the atlas is complete, and the edges of these 

 facets are raised. The inferior lateral process is flat, broad, and strongly bent 



backward. 



Second cervical: Inferior lateral process nearly as long as that of the first 

 cervical ; broad, flat, and bent backward parallel with the process of the first cei-vical. 

 Superior lateral process short, strong, and flat. A large incomplete foramen between 

 it and the inferior process.
