BORRADATLE—STOMATOPODA. 213 
larger and nearly reaches the end of the endopodite, but falls far short of the end of 
the exopodite. 
Length of the largest specimen 55 mm. 
Two specimens dredged, E 11, Amirante Group, 25 to 80 fathoms. 
Genus PSEUDOSQUILLA, Dana, 1852. 
11. Pseudosquilla ciliata (Fabr.), 1793. 
Squilla ciliata, Fabricius, Ent. Syst. ii. i. p. 512 (1793). 
Pseudosquilla ciliata, Miers, Ann. Mag. Nat. Hist. (5) v. p. 108 (1880) ; Brooks, ‘ Challenger ’ 
Report, Stomatopoda, p. 53, pl. 15. fig. 10 (1886) ; Borradaile, Willey’s Zool. Results, iv. 
p. 402 (1900). 
This species may be distinguished from the nearly related Indo-Pacific species ornata, 
oculata, and oxyrhyncha by the following characters :— 
i. There are no eye-spots. 
ii. The rostrum is larger than in the other species, but has no spine. 
iii. The eyes are cylindrical. 
iv. The third free thoracic segment is not so sharply truncated at the sides as in 
the other species. 
v. The last joint of the exopodite of the uropod equals or outreaches the last spine 
of the outer edge (except in some small individuals), and outreaches the 
inner basal spine. 
From the Atlantic form (occidentalis, Borr., 1900) described by Brooks (Joc. cit.), it 
differs in having no spine at the hinder angle of the fourth abdominal segment, and the 
inner basal spine of the uropod longer than the outer. 
Tt is not clear whether the true P. ciliata is found in the Atlantic. 
Specimens taken at various depths down to 34 fathoms in the Seychelles, Diego 
Garcia, Zanzibar, and Wasin, British East Africa. 
12. Pseudosquilla ornata, Miers, 1880. 
Miers, Ann. Mag. Nat. Hist. (5) v. p. 111, pl. 3. figs. 5, 6 (1880). 
This species differs from its near congeners as follows :— 
i. Eye-spots are usually present and defined by a white ring, but they may he 
replaced by a single median spot of like nature or wanting altogether. 
ii. The rostrum is shorter than in P. ciliata, but has no spine. 
iii, The eyes are broad and flat. 
iv. The third free thoracic segment is square at the sides. 
v. The last joint of the exopodite of the uropod is short and outreached by the last 
spine of the outer edge, but outreaches the inner basal spine. 
Specimens from Coetivy, Seychelles, and Salomon, Chagos. 
P. oxyrhyncha, Borr., 1900, differs from this species in having the eye-spots not 
defined by a white ring, a spine on the rostrum, and the last joint of the exopodite of 
the uropod outreached by the inner basal spine.
