II. Geological Succession (p. 555). The North-American fossil 
Estheric, namely E. pulew, Clarke, ovata, Jones, and Dawsont, Packard 
(not Dawsoni, Jones), and Leaia Leidyi (Lea), are here enume- 
rated, with their descriptions ; and a general Table of Rupert Jones's 
species (1862) is given, with Branchipus from the Isle of Wight 
added. This might have been augmented with other Hstheri@ and 
Leaiw from many sources of later date, as, for instance, the follow- 
ing (all Carboniferous) :— 
Estheria Adamsii, Jones, 1870. 
Dawsoni, Jones, 1870. 
—— Freysteni, Geinitz, 1879. 
limbata, Goldenberg, 1877. 
Peachii, Jones, 1870. 
—— punctatella, Jones, 1865, 
—— rimosa, Goldenb., 1877. 
rugosa, Giimbel, 1864. ” 
Leaia Jonesii, R. Etheridge, Jun., 1879. 
Kliveriana, Goldenb., 1873. 
—— Leidyi, var. Baenschiana, Geinitz & Beyrich, 1864. 
—— tricarinata, Meek & Worthen, 1869. 
The general succession of the Crustacea is also illustrated by a 
tabular diagram (p. 361). 
At page 361 Mr. Packard offers the following observations on the 
geological appearance and succession of the lower forms of Crusta- 
cea. “ Simultaneously with the appearance of the larva-lhke Agnostus 
and the more highly organized Paradoaides &c., we find in the 
Lingula-flags the remains of a species of Phyllocarida, the Hymeno- 
caris vermicauda. Mr. J. W. Salter, who was the first author to 
draw attention to the close relations of the fossil genera Hymenocar's,
