over all the median portions of the carapace and abdomen. On these areas the 
punctuation is so coarse and so close that the surface stands up as a sharp mesh-like 
reticulation which obscures the median and submedian carinae (fig. 48). 
The breadth of the carapace measured behind the antero-lateral angles is about 
half its length, excluding the rostrum. The median carina, which owing to the reti- 
culation of the surface can only be traced with difficulty, extends throughout the 
length of the carapace and is bifurcated anteriorly for about half its length in front 
of the small but distinct dorsal pit; it is also deeply bifurcate posterior to the sharply- 
defined cervical groove. The lateral and intermediate carinae are more distinct. The 
antero-lateral angles are produced as sharp spines that fail to reach the level of the 
rostral base and the lateral margins are obtusely angled in front of the postero- 
lateral corners. 
The rostrum is fully as broad as long and its lateral margins are upturned and 
‘converge to an evenly rounded extremity. The dorsal surface is rugose and bears a 
sharp median carina in its anterior two-thirds. 
The eyes are very small. The corneais about as wide as the basal portion of the 
stalk and the internal margin of the latter is dilated and ridged. The corneal and 
peduncular axes are very slightly oblique.' The ophthalmic somite is produced ante- 
riorly as a short rectangular process between the bases of the eyestalks. The anten- 
nular peduncle is unusually long, greatly exceeding the combined length of the cara- 
pace and rostrum. ‘he dorsal processes of the antennular somite are pitted and 
reticulate dorsally. The mandibular palp is present and is composed of three segments. 
The outer inferior edge of the merus of the raptorial claw is pitted externally 
and is distally rounded. There are two parallel and connected ridges forming an H- 
figure on the outer aspect of the carpus. The dorsal carina is entire and terminates 
abruptly before reaching the anterior margin. The propodus bears the usual three 
movable spines and the row of pectinations on the margin opposed to the dactylus. 
The latter is provided with six slender teeth including the apical one and the 
external margin, which shows only the faintest traces of sinuation, is bluntly angled 
proximally. 
The last three thoracic somites (fig. 48) are furnished with submedian and inter- 
mediate carinae, the former being very indistinct. The lateral margin of the fifth 
somite is deeply bifurcated and consists of two subequal spines, the anterior of which 
is sharper and situated on a lower plane than the posterior and points almost straight 
forwards. ‘The sixth thoracic somite is deeply bilobed laterally; the lobes are greatly 
expanded, coarsely pitted and are of about equal length and breadth: the anterior is 
distally truncate while the posterior is rounded at the apex. In the seventh somite 
' The eye in S. foveolata is very peculiar. In other species of Squilla the long axis of the cornea is 
usually in the same plane as the longest transverse axis of the stalk, but in the present case the cornea is 
twisted and its inner end is, in relation to the stalk, subdorsal. ‘The cornea, as mentioned above, is set 
rather obliquely on the stalk; but this obliquity is the reverse of that found in most other species, 
for the inner margin of the stalk is a trifle shorter than the outer.
