554 H. WOODWARD ON FOSSIL CRUSTACEA, 
thin slabs of which such rich and varied fish-remains have been 
discovered. 
The fossil lies upon its left side, and exhibits the cephalic shield, 
with the eyes, antennules, antennee, and the great recurved mono- 
dactylous maxillipeds, m, m (one of which is displaced and les on the 
opposite side). The thoracic and abdominal somites are much com- | 
pressed. Only a trace of the thoracic limbs is seen. None of the 
other paired appendages are preserved until the twentieth pair, which 
have the characteristic form and serrated outer border(s) to the pe- 
nultimate joint peculiar to modern Squilla. The terminal palette 
of this swimming-foot is lost (as is also the case with the specimens 
from Solenhofen) ; but this is, no doubt, due to the weakness of its 
articulation to the penultimate joint. 
The telson was ornamented with a spinose border ; but it is not 
sufficiently well preserved to be described in detail. The segments 
of the abdomen are smooth, and nearly of equal size, the posterior 
ones being the broadest. 
The borders of the epimera are without spines, and quadrate in 
form. The segments are smooth, not being divided by epimeral or 
tergal ridges as in the modern Squwilla, in this respect resembling 
Coronis and Gonodactylus; yet the presence of the great toothed 
second pair of maxillipeds certainly affines it to Squilla rather than 
to one of the allied genera. Like the Kocene form from the London 
Clay, it is probably nearly related to the widely-distributed S. 
Desmarestit. 
In point of size this Cretaceous form agrees closely with the spe- 
cles described from Solenhofen (see Pl. XXVI. fig. 5); but the 
segments of the Jurassic form are all highly ornamented with spines 
and costa, whereas the later Cretaceous form is destitute of orna- 
mentation on the segments.

I dedicate this interesting specimen to Prof. EK. R. Lewis, F.G.5., 
the discoverer, naming it Squilla Lewisu. 
IV. On the Occurrence of a Fossil King-crab (Limulus syriacus) tn the 
Cretaceous Formation of the Lebanon. (Plate XXYVI. fig. 6.) 
The proposition that if any animal be found, both in a living state 
and also fossil in some early formation, it may justly be con- 
cluded that it has survived during the period represented by the
