Sunier is inclined to think that S. stonypetes is merely based 

 on young individuals of S. quinqncdentAta, but we are unable to 

 agree with this view. Apart from other characters the corneal 

 and peduncular axes of the eye are more oblique in S. gonypetcs 

 than in the related species, and it appears to be a general rule 

 that in those forms which possess oblique eyes, the cornea is 

 more transversely' placed in the young than in the adult. 



The question cannot, however, be settled definitely with the 



material at present in existence. As Sunier has pointed out, the 



known specimens of S. quinqiiedcntaia all exceed 100 mm. in 



length, whereas the largest example of S. qonypetes is only 55 mm. 



in length.

Sunier has recorded this species from Anjer in the Sunda 

 Straits, thus greatly extending our knowledge of its geographical 

 range. Tne only additional specimens we have seen are from the 

 western side of the Bay of Bengal. 



Squilla mikado, sp. nov. 



1913. Squilla striiiulans, Kemp, loc. cit., IV, p. 78 (in part). 



In 1913 one of us doubtfully attributed to Wood-Mason's 

 S. strididans a single specimen of Squilla found at Misaki in 

 Japan. A second individual which Dr. Annandale obtained in 

 1915 from the Misaki laboratory proves that the Japanese form, 

 though nearly related to that found in the Bay of Bengal, must 

 be regarded as distinct. 



The principal characters in which the two species differ are 

 the following : — 



S. slridulans, Wood-Mason. ! S. mikado, sp. nov. 



Undivided portion of mid-dorsal j Undivided portion of mid-dorsal car- 



carina of carapace, anterior lo dorsal 

 pit, less than one-third as long as bifur- 

 cated portion (text-fig. la). 



Rostrum with an obscure mid-dorsal 

 tubercle (text-fig la). 



Cornea much dilated and set very 

 obliquely on eyestalU (lext-fig; ib). 



Lateral processes of sixth and seventh 

 thoracic somites shorter and broader 

 (text-fig. ic). 



Surface of .ibdominal somites finely 

 rugose. 



ina of carapace, anterior to dorsal pit 

 about half as long as bifurcated por- 

 tion (text-fig. 2a).

 carina (text-fig. 2a). 



Cornea less dilated and set much less 

 obliquely on eyestalk (text-fig. 26). 



Lateral processes of sixth and seventh 

 thoracic somites longer and more slender 

 (text-fig. 2c).
