ADDENDUM. 



Since the preceding report has been in press I have had an opportunity of visit- 

 ing Kilakarai and Pamban in the Ratnnad District, S. India. During the first half 

 of the tour I was fortunate in being accompanied by Dr. J. R. Henderson, Superin- 

 tendent of the Madras Museum : it was in localities at no great distance from those 

 that we visited that Dr. Henderson, some twenty-four years ago, made a great part 

 of the extensive collections of Crustacea which he subsequently described in the 

 Transactions of the Linnean Society (1893) under the title f ' A Contribution to Indian 

 Carcinology." 



The fauna of the district seems to be one of almost inexhaustible richness 

 and during the comparatively short period in which we were collecting, we succeeded 

 in obtaining nine species of Stomatopoda, including several scarce forms; we were 

 also able to make a few interesting observations on the habits of Gonodactylus . 



Squilla quinquedentata, Brooks, [p. 52.] 

 Judging by the number of specimens hitherto found in Indian waters this species 

 appears to be very scarce, but three large individuals, two males and one female, 

 ranging from 117 to 125 mm. in length, were obtained from the fishermen at 

 Kilakarai. 



The specimens differ in a few unimportant details from those previously 

 described. In two examples the anterior bifurcated portion of the median carina of 

 the carapace is distinct, but interrupted and non-existent at its proximal end as in 

 Squilla inter rupta and in 5. oratoria var. pevpensa. In all the specimens the anterior 

 margin of the ophthalmic somite is feebly emarginate and the posterior lobe of the 

 fifth thoracic somite is acute. The lateral carinae of all the abdominal somites end 

 in spines, the intermediate teeth of the telson are only very slightly inturned and 

 there are four submedian denticles, eight or nine intermediate and one lateral. The 

 colouration of the living specimens was not distinctive, the dark patches noticed in 

 the previously recorded examples at either end of the median carina of the telson 

 being indistinguishable. 



Squilla nepa, Latreille. [p. 60.] 

 Found in abundance by the fishermen at Kilakarai. The largest specimen seen 

 was a female 134 mm. in length; small individuals, including one only 21 mm. in 

 length, were caught among weeds close to the shore. 



Squilla holoschista, Wood-Mason, MS. [p. 64.] 

 Not uncommon in fishermen's nets.
