which are found in S. slridulans, but they entireh' lack the black 

 pigmentation on the posterior margins of the abdominal and 

 exposed thoracic somites which is characteristic of tlie latter 

 species. 



In S. mikado, as in S. siridiilans, the two lobes found in manj- 

 species of Squilla on either side of the fifth thoracic somite are 

 replaced by two sharp spines and the lateral carinae of the first 

 five abdominal somites are bicarinate. These two characters alone 

 are sufficient to distinguish them from all other species of the 

 genus.

In 1913 comparison was drawn between a specimen of this 

 species from Japan and one obtained on the Burmese coast by 

 Messrs. Simpson and Rudmose Brown and kindly lent by Mr. A 

 Patience. An additional specimen has since been found on the 

 Burmese Coast by the ' Investigator,' but it is unfortunately in 

 poor condition, having lost both raptorial claws. 



We are unable to compare this individual with that previously 

 recorded from Burma, as the latter has been returned to Mr. 

 Patience, but it differs from the Japanese example in all the 

 characters pointed out in 1913, except that (i) the subraedian 

 carinae of the last abdominal somite are tricarinate, the three 

 keels meeting posteriorly, and that (ii) of the carinae which termi- 

 nate in the submedian teeth of the telson edge only that on the 

 right hand side is bifurcate. On close comparison with the Japan- 

 ese specimen a number of minor distinctions in sculpture are to 

 be found. 



We think it probable that the Burmese form is distinct from 



that found in Japan, but we are unable to draw up a specific 



definition from a single imperfect specimen that shows signs of 



immaturity.

The carinae of the carapace (text-fig. 3) are less numerous 

 than in the ahied form and are frequently interrupted and broken 

 up into series ot short carinulae or tubercles. In the anterior
