84 ICHTHYO PTERYGIA. 



Soc), pt. iii. pi. xxxii. fig. 1. The entire length of this 

 specimen is about 11 feet 4 inches. The skull is crushed 

 and has lost the extremity of the rostrum ; but exhibits 

 the contour of the orbits. The entire series of vertebral 

 centra, as well as the ribs, are well shown, but the neural 

 spines are not apparent. The greater portion of the pec- 

 toral limbs is shown, but of the pelvic limbs only the 

 right femur remains, although the left limb is introduced 

 in Owen's figure. The teeth seem to be small ; and the 

 extremity of the rostrum is wanting. No history. 



2008 *. Slab exhibiting the ventral aspect of the skull and the left 

 {Fig.) lateral aspect of the greater portion of the vertebral co- 

 lumn ; from the Lower Lias of Street, near Glastonbury, 

 Somersetshire. Figured in Hawkins's ' Sea Dragons,' 

 pi. xii. The skull is very imperfect, but the teeth are 

 shown in the basal portion of the rostrum. The anterior 

 portion of the vertebral column is wanting, but the 

 posterior dorsal and caudal region is well preserved. The 

 pectoral limbs are absent, and the pelvic are somewhat 

 broken up, one of them being thrown across the vertebral 

 column. Haivkins Collection. Purchased. 1834. 



R. 498. Slab exhibiting the dorsal aspect of the entire skeleton of 

 a medium-sized individual ; from the Lower Lias of Street. 

 The only loss that this specimen has sustained consists of 

 a few phalangeals and the terminal caudal vertebrae. The 

 skull is somewhat crushed, but exhibits the equilateral con- 

 tour of the supra temporal fosste, and the parietal foramen. 

 There are four rows of phalangeals in the pectoral limb ; 

 two series of bones articulating with the ulnare. There 

 is a small notch in the left radiale, but none in the right.
