REPORT ON THE STOMATOPODA.

In this larva, which is 1 inch long, the carapace makes, with the rostrum, - fo° 0 ° 0 , the 
exposed hind body and the telson of the total length. 
Even if the close resemblance between this larva and the one from which Faxon 
reared a young Squill a empusa did not indicate that Alima bide ns is also a Squilla, 
this could be inferred with great certainty from the examination of the larva itself, since 
it resembles the adults of this genus in the presence and in the small number of spines 
on the inner edge of the dactylus of the raptorial claw, in the depression and width of the 
hind body, in the presence of a median-dorsal carina on the carapace and on the telson, 
in the presence of acute spines on the postero-lateral angles of the abdominal somites, in 
the presence and in the small number of marginal spines on the outer edge of the proximal 
joint of the exopodite of the uropod, in the relative length of the two spines of its ventral 
process, in the presence of a secondary tooth on the outer edge of the inner and longer 
spine, in the relative positions of the marginal spines of the telson, in the presence of a 
single minute dentation inside the base of the lateral, and a number of dentations (more 
than three) between the intermediate and the submedian. While it is true that there 
are some adult Squillse which do not shew all of these characteristics, and while no one 
of them is in itself perfectly diagnostic, it is also true that there are no Stomatopods in 
which they are all united except members of the genus Squilla, and we may therefore 
decide, with all the certainty which is possible in absence of direct proof, that Alima 
bklens is the larva of one or perhaps of two species of the higher carinate Squillse. 
The presence of three secondary spines on the inner edge of the postero-lateral 
spine of the carapace of Claus’s larva, and of only two in our specimen, possibly corre- 
sponds to a specific difference between the adults. 
Alima macrophthalma. — The Challenger collection contains a number of specimens of 
an Alima larva of a type which is quite different from that of which Alima gracilis is 
an example, and I have selected from a surface gathering, made near Cape Howe, the 
series which is shown in PI. VII. figs. 1-6 ; PI. VIII. figs. 1-3. 
It is possible that these are not all of one species, but the differences between them 
are so slight that, if not the same, they must at least belong to adults which are 
very closely related, and as I am not able to identify the larva with any of the published 
descriptions, 1 propose for it the provisional name Alima macrophthalma, on account of 
the great size of the eyes as compared with the very small eye stalks. 
The youngest larva which I have found, No. 1, is essentially like No. 2. The telson 
is shown in PI. VII. fig. 2 ; No. 2, which is shown in PL VII. fig. 1, is 4^y mm. long; 
No. 3, shown in fig. 4, is 6^- mm. long; No. 4, shown in fig. 5, is 8 x 4 o mm. long; 
No. 5, shown in PI. VIII. fig. 1, is 8 T 7 ^ mm. long ; No. 6, shown in fig. 2, is 11^ mm. 
long, and No. 7, shown in PI. VIII. fig. 3, is 19 mm. long. 
The most prominent diagnostic characteristics of Alima macrophthalma are as 
follows. The eye-stalks are very short, and the eyes large with very broad tips ; the
