MESOZOIC TIjVIE — TEIASSIC AND JURASSIC.

of Woodward. Fig. 1307 is one of the Macrurans from Solenhofen, and 

 1308, an Isopod related to the modern Oniscus, from the Purbeck beds of 

 England. A species of Astaais, or Lobster, is reported from the Lias. 

 Fig. 1310, though Spider-like, is a Stomapod Crustacean. 



1306-1310. 



ABTicrLATES. — Fig. 1306, Libellula ; 1307, Eryon arctiformis ; 1308, Archseoniscus Brodiei ; 1309, elytron or 



wing-case of Buprestis ; 1310, Palpipes priscus. 



Insects of all the prominent tribes, even those of Dipters and Hymenopters, 

 occur as early as the Lias ; and the Hymenopters belong to one of the higher 

 divisions, that of the Ants. A Lias species of Ant is the PalcBomyrmex 

 •prodromus of Heer, from Switzerland. Two other related species were 

 described by Woodward from the Purbeck of England. Fig. 1306 represents 

 a Dragon-fly, and 1319 a Beetle's wing-case (a Buprestis), both from Solen- 

 hofen ; and another Dragon-fly, Libelhda Brodiei, is from the Upper Lias of 

 England. 



Vertebrates. — The Jurassic Vertebrates included Birds, as well as 

 ■Fishes, Reptiles, and Mammals. 



1. Fishes. — The Fishes were Ganoids and Selachians. Two genera are 

 illustrated in Figs. 1311, 1312. Pycnodus had many species, and also, among 

 Selachians, Hyhodus, Acrodus, Stropliodus ; and among Ganoids, Lepidotus, 

 and others. The Ganoids most nearly related to the Teleosts are those of 

 the Amia family, of Pike-like form, species of which occur at Solenhofen. 

 The Amioids have been referred to the Teleosts, but are now regarded as true 

 Ganoids.
