It will be noticed that under the records of typical S. ovatoria 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 S. 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 S. oratoria 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 :—
