50 ICHTHIOPTEKYGIA. 



The coracoids, clavicles, left scapula, and the nearly entire 

 paddles of both sides are shown. The first row of 

 phalangeals are of the elongated form and have the entire 

 anterior border characteristic of the present species. 



No history. 



R. 1069. Cast of an imperfect pectoral girdle and the proximal 

 portion of the right limb, together with several vertebral 

 centra, not improbably belonging to this species. The 

 original was probably obtained from Lyme-Regis and is 

 preserved in the Paris Museum. The coracoids are pre- 

 served, but their posterior expansion is broken away, which 

 causes them to appear relatively longer and narrower than 

 they really are. The right scapula and clavicle together 

 with the interclavicle are also preserved. In the limb the 

 humerus, radius, ulna, and intermedium are preserved ; 

 the radius having the entire anterior border characteristic 

 of the present group. 



Mantell Collection. Purchased, 1838. 



R. 224. Slab exhibiting the ventral aspect 1 of a nearly entire left 

 pectoral limb probably belonging to a large individual of 

 this species ; from Lyme-Regis. The extreme length is 

 0,508. There are seven longitudinal rows in the widest 

 part, and four bones in the third transverse row. 



Purchased, 1882. 



R. 1063. Slab exhibiting the dorsal aspect of the greater portion of 

 a left pectoral paddle agreeing closely in size with the 

 preceding specimen ; from Lyme-Regis. The humerus 

 and the distal phalangeals are wanting. There are but 

 three oblong bones in the third row. No history. 



R. 1064. Slab showing the dorsal aspect of both pectoral limbs of an 

 individual agreeing nearly in size with No. 41849 (p. 42) ; 

 from Lyme-Regis. The distal bones are wanting, and 

 there are four oblong bones in the third row. No history. 



R. 587. Slab exhibiting the entire right pectoral limb of an indi- 

 vidual agreeing in size with the preceding ; from Lyme- 

 Regis. Eight rows can be counted in the middle. The 

 humerus is imperfect. Purchased, 1885. 



1 It is not always easy to determine which surface of a paddle is exposed ; 

 if in any of the following specimens the surface should be wrongly deter- 

 mined such specimen will belong to the side opposite to that stated.
