anatomy of the mole- cricket. 
in the form of a distensible and longitudinally folded tube of 
a reddish brown colour ; it then passes on among the muscles 
of the two hind pair of legs, and at length terminates in a 
very large crop of an oval form. In the vicinity of the 
mouth it is surrounded by muscles which arise from its outer 
coat, and are inserted at nearly right angles into the adja- 
cent parts ; these muscles of course serving to open and 
distend it. 
In the crop itself two sets of muscular fibres are very 
easily discernible, some running in the direction of its length, 
others surrounding it in the opposite direction ; and it is 
lined by a very thin membrane having a cuticular character. 
The tube which passes from the crop towards the intes- 
tines commences so near the termination of the esophagus, 
that externally it appears to be a continuation of the latter ; 
it is very thick and strong in comparison with its diameter, 
and consists of a coat of muscular fibres disposed circularly, 
lined by a membrane which has evidently a glandular cha- 
racter. This tube terminates at a short distance from its 
commencement in a small organ, scarcely larger than a 
hemp-seed, which may very properly be called a gizzard ; 
though more complicated in its structure, and more effectual 
for the intended purpose than the gizzard of any bird. 
The form of the gizzard is nearly spherical, and it consists 
of a thick external muscular coat, which is lined by a glan- 
dular membrane of very singular construction ; the inner 
surface being divided longitudinally into six equal parts, 
separated from each other by two horny ridges of a dark 
brown colour ; each division is furnished with three series of 
serrated teeth, of the consistence of tortoise-shell, and nearly
