of the terminal segment is thickened and obtuse posteriorly ; the lateral marginal 
spines are obsolete, and the intervening denticles are small and not acute. The eye- 
peduncles have their inner margins straight and are convex only on their outer surface.”’ 
S. votundicauda may be distinguished from all the species of the microphthalma 
and Jatreillei group by the absence of the spines at the antero-lateral angles of the cara- 
pace. The posterior thickening of the median carina of the telson (in the female) 
also appears to be a noteworthy feature. 
It should be noticed that the rostrum of Miers’ specimen of S. microphthalma 
seems to have been unusually short. 
The type specimen, a female 70 mm. in length, was found at Formosa.

The dorsal surface of the carapace and abdomen is smooth and highly polished. 
The carapace, measured behind the antero-lateral angles, is half, or rather more than 
half, its length, excluding the rostrum' (fig. 21). The lateral margins are not angulated 
in front of the postero-lateral corners. Between the gastric grooves and the margins, 
in the anterior half of the carapace, there is on each side a shallow groove ; the median 
and intermediate carinae are entirely absent® and the lateral and marginal are only 
visible in the posterior quarter of the carapace. The antero-lateral angles are pro- 
duced as strong spines that reach almost or quite as far as the level of the rostral base. 
The rostrum is smooth dorsally, scarcely broader than long, and its lateral margins, 
which are not upturned, converge to a rather sharply rounded apex. 
The cornea of the eyes is not large but is very clearly wider than any part of the 
stalk ; the greatest breadth (across the cornea) is equal to about three-quarters of the 
total length. The corneal and peduncular axes are very slightly oblique. The anten- 
nular peduncle is about as long as the carapace, excluding the rostrum. The two 
basal segments of the antennal endopodite are short and do not reach much beyond 
the middle of the scale. The mandibular palp is present and three-segmented. 
The outer inferior margin of the merus of the raptorial claw terminates in a 
rounded angle ; the carpus has a groove and keel on its external aspect and its dorsal 
! Brooks’ figure is, I believe, incorrect in showing the carapace so very much narrowed anteriorly. 
* In fig. 21 the representation of a groove on either side of the gastric grooves erroneously bears 
some resemblance to an intermediate carina.
