IC)I3-] S. Kemp: Crustacea Stomatopoda of the Indo-Pacific Region. 71 



It will be noticed that under the records of typical 5. oratoria are included four 

 examples from the British Museum collection in which the median carina of the carapace 

 is partially or completely discontinuous. There is reason to believe that one of these 

 examples (that from Amoy) is wholly abnormal ; the others are in this respect, and in 

 this respect only, intermediate between the typical form and the variety. 



In the entire absence of tubercles on the dorsal carina of the carpus, the var. 

 perpensa resembles some very young individuals of 5. oratoria, s.S., but in the former 

 the character persists throughout life and in all examples except the four mentioned 

 above it is found in association with a discontinuous median carina. 



The Indian specimens present scarcely any perceptible difference from those 

 found in S. China, except that in examples from the latter locality the breadth of the 

 cornea is perhaps a trifle less and the dorsal punctuation frequently rather more pro- 

 nounced. 



The colour of spirit specimens is not characteristic. In recently caught examples 

 from Tuticorin the posterior margins of the last three thoracic and all the abdominal 

 somites are defined by dull greenish pigment. The submedian post-abdominal carinae 

 are of a similar colour, as are also those of the carapace and the median and marginal 

 carinae of the telson. The spines of the telson and of the ventral process of the uropod 

 are tipped with bright rosy red and in many specimens suffused patches of the same 

 colour are visible on the abdomen between the submedian, intermediate and marginal 

 carinae and on the free thoracic somites external to the intermediates. The outer sur- 

 face of the raptorial merus is also rosy red and traces of the same tint are frequently 

 visible on the carapace. The inner half of the outer uropod is dusky and the eyes are 

 brown. 



I have examined one hundred and fifty- two specimens of 5. or atoria var. perpensa, 

 and in this series the constancy of the characters noted above is most remarkable. 

 In the Indian Museum are one hundred and forty-six examples : —
