1913. ] S. Kemp: Crustacea Stomatopoda of the Indo-Pacific Region. 55 
The colouring of the telson is much the same as in the preceding species, but that 
of the abdomen is different. The proximal half of the second abdominal somite bears 
a prominent transverse black patch extending laterally as far as the sinuous groove 
between the submedian and intermediate carinae and there is also, on the posterior 
half of the fifth abdominal somite external to each submedian carina, a large well 
defined quadrate black spot (fig. 44). 
Four specimens in the Indian Museum agree in possessing the above characters :— 
346 Off Andaman Ts.; 60 fms. ‘Investigator.’ 1¢,56mm.; 12,36mm. TYPES. 
3859 Off Cheduba, Arakan Coast; 7 fms. ‘Investigator.’ Io, 49 mm. 
= Persian Gulf; 47 fms., 26°24’ N., 56°2’ E. ‘Investigator.” 12, 26 mm. 
I also refer to this species a single specimen which differs from the rest in having 
the anterior bifurcated part of the rostrum fine but distinct, and absent at the point 
of junction with the single posterior part of the carina (as in S. imterrupta) ; the ros- 
trum also is subtriangular, the margins distinctly more convergent than in typical gomy- 
petes and the intermediate carinae of the third and the laterals of the fourth abdominal 
somites do not terminate in spines. In other respects the specimen bears the closest 
resemblance to those listed above. 
75386 
i Off Vizagapatam Coast, Madras; 20 fms. ‘Investigator.’ 19, 47 mm. 
Two specimens from the British Museum collection (recorded by Pocock under 
the name of Squwilla affinis) have also been examined, and one, which is identified with 
some doubt, kindly lent by Mr. A. Patience :-— 
Holothuria Bank, China Seas, 53 fms. H.M.S. ‘ Penguin.’ 292, 25 and 37 mm. 
Mergui Archipelago. Simpson and Rudmose Brown. I, 33 mm. 
Two of these three specimens have lost their raptorial claws and in them the 
median carina of the carapace resembles that of the example from the Madras Coast. 
The other individual (China Seas, 25 mm.) is perfect and is quite typical.

This very distinct species may be readily distinguished from both the preceding 
by the following characters :— 
1. The rostrum bears a sharp median longitudinal carina. 
2. The eyes (fig. 45) are enormously swollen and expanded ; the breadth of the 
cornea is considerably more than one-third the length of the carapace and 
the cornea of the eye is a trifle more transversely placed than in adults, while there is very little differ- 
ence in the form of the thoracic lobes. 
1 T have not seen this publication and have no knowledge of the precise date at which it was issued. 
The paper is, I believe, in the Japanese language.
