Extract

Dr. Packard's observations on the structure of the Phyllopoda, and his comparative anatomical studies of allied living and extinct genera, supply the palæontologist with sound reasoning for referring the Phyllocarida to the Nebaliad type as a centre for a great group of obscure fossil forms, and as a starting-point for the Decapoda. His views have been referred to in some detail in the Geol. Mag. for August last, pages 349–352.

Pal. Foss. pl. E, fig. 7) from Leintwardine, under the name Lept. leptodactylus.… If this approximation prove correct, the fossil should in future be called Leptocheles Murchisoni (Ag. sp.).”—Q. J.
