386 Dr. H. Woodward—On a New Lias Crustacean. 
Rural Dean, and Vicar of Rowington, near Warwick, I have received 
a block of Lower Lias Limestone from the “ Insect-bed” (Ammonites 
planorbis-zone) at Wilmcote, containing a very well-preserved 
specimen of a Macrourous-Decapod Crustacean referable to the 
genus ger of Miinster. 
The specimen was obtained by the Rev. H. E. Lowe, M.A., 
residing at Wilmcote, who procured it from one of the quarrymen, 
and afterwards generously presented it to Mr. Brodie. 
Like similar fine-grained fissile limestones, such, for instance, as 
the Lithographic Stone of Solenbofen in Bavaria, these Lias beds 
divide up into more or less numerous layers, the fossil-remains being 
exposed as impressions and counterparts, upon the corresponding 
surfaces of the slabs when split along their lamine. In this instance, 
however, only the single slab containing one side of the organism, 
has been preserved, so that some parts of the surface of the body- 
segments and appendages, which had adhered to the counterpart, 
have been lost with it. 
The specimen, which is of the bigness of an ordinary-sized prawn 
—the body being 44 inches in length—is lying upon its left size. 
Its rostrum, which is not serrated, is exceedingly slender, and as 
long as the entire carapace. The right ophthalmite, and its peduncle, 
are very well preserved. Only traces of the first or inner pair 
of antennze can be detected ; but the outer antenne, with their long 
multiarticulate filaments, can readily be observed, together with the 
prominent spine near the base of the same that gives support to the 
long oval antennal scale, the impression of which can also be 
clearly made out. Next is seen a pair of extremely long spinigerous 
maxillipeds, with simple non-chelate extremities, their four distal 
joints armed with two rows of long, sharp, and slender articulated 
spines arranged at regular distances apart along each border. 
Next follows the first pair of walking-legs, which are slender and 
shorter than the maxillipeds, and are provided with chelate termina- 
tions. The second pair of legs are also chelate, and similar to the 
first. The third pair are broken off near the body. The fourth and 
fifth pairs of limbs are long and very slender, and have likewise 
simple monodactylous terminations. 
The carapace is twice as long as it is deep, its surface smooth, and, 
where preserved, of a rich brown colour. Just over the branchial 
region the carapace (branchiostegite) is wanting and we see exposed 
the vertical ridges of the calcified endophragmal system, consisting of 
the infoldings of the lateral walls of the thorax, to which the legs 
are articulated, and which give attachment to the muscles of the 
limbs, and upon the outer face of which, but covered by the over- 
arching branchiostegite, the branchie or gills were situated. 
The specimen measures 106 millimétres in length by 40 mm. in 
depth, and displays the cephalothorax 53 mm. long by 20 mm. in 
depth, the rostrum being 24 mm. long, the pedunculated ophthal- 
mite 4mm. long. 
Behind the cephalothorax are seen the six abdominal segments of 
nearly uniform size, the last supporting the ‘telson’ or terminal
