TUE GEOLOGIST. 
Leaving the vegetable kingdom and ascending to tliat of the ani- 
mal, "we find in these beds but few zoophytes, these organisms being 
chiefly confined to the upper division of the Bath Oolite already 
mentioned. The Annelida are represented by a small serpula, and 
the Crustacea by a small lobster (Ghjpliia rostmta), and a small spe- 
cies of crab (Erijon) not yet named. Faint but unmistakable relics 
appear of that depai'tment of animal life usually regarded as the 
most frail and perishing, namely the class of insects ; nevertheless, 
the remains of primeval beetles and dragon-flies are preserved in the 
fossil state. The most frequent specimens of this kind are the elytra, 
or wing-cases of beetles allied to the Buprestidaj, or Pi-ionida3, races 
which abound in warm, but are not excluded from temperate, climates. 
The Oxford Museum contains the wing of a neuropterous insect 
allied to the dragon-fly, most elaborately described by Dr. Buckland, 
and likewise the hind-leg of a species of Curculio, exhibiting the 
peculiar adaptation for leaping. 
Having noticed the insects, the MoUusca, or shell-fish, now claim 
our attention, and we remark their number to be comparatively 
limited. The Brachiopoda are represented by two species of Rhyn- 
chonella (li. concinna and It. ohsoletci). Among the Monomyarian 
bivalves may be enumerated three species of Gervillia ((?. acuta, G.' 
suhcijlindrica, and G.ovata), tlrree of Lima (L. impressa, L. duplicata, 
and L. prohoscidea), two of Inoceramus {I. oMiquus and I. aimjgda- 
loides), two of Pinna (P. ampla and P. cuiieata^, three of Pecten 
(P. lens, P. annidaf iis, and P. vagans), one of Perna (P. rugosa), and 
several species of Ostrtea, the best defined of which are 0. acuviinata 
and 0. Soicerhli. The Dimyarian bivalves also comprise several 
genera distributed as follows : — Two species of Modiola {M. plicata 
and M. imjjlicata) , two of Pholadomya (P. acuticosta and P. Murclii- 
sordi ?), two of Trigonia {T. Moretouil and T. impressa,), the latter 
being highly characteristic of this formation, and occurring in great 
abundance, its opened valves completely covering the surfaces of 
many of the slates; one of Mytilus (M. sublcevis), one of Cardium 
(C. acutangiduni) , also a species of Unicardium and My a calcei- 
formis (?) The Gasteropodous univalves include Alaria trifida, 
Patella mgosa,P. Romeri two species of Natica, one of Actce.onina, 
one of Turho, and a small Ncrita, which often retains very distinct 
traces of the black and yellow bands of colour that adoraed its shell. 
The Cephalopoda are represented by but few species, and individually 
they exhibit an equal paucity of numbers ; we may, however, enu- 
merate Belemnites fusiform is and B. Bessinus, associated with Nautilus 
Baberi and Ammonites gracilis, with the cast of another Ammonite, 
too imperfect for identification. 
Still ascending in ,the scale of animated beings, the fossil fishes of 
Stonesfield come under our consideration. The gi^eater number of 
these have been described by Agassiz, and constitute a large and 
extremely interesting group, although rarely more than fragmentary, 
and chiefly represented by the teeth, scales, and " spears," as the 
workmen term the ichtliyodorulites, with a true rendering of the
