Squilla scorpio, Latreille. 
1913. Squilla scorfio, Kemp, Mem. Ind. Mas., IV, p. 42, pi. ii, fig. 30. 
Five specimens are in the collection, the largest a male 75 mm. in length. 
Apart from the fact that the lateral carinae of the fourth abdominal somite occasion- 
ally terminate in spines, the .specimens agree exactly with the description in the paper 
quoted above. 
var. immaculata, Kemp. 
1913. Squilla scorpio var. immaculata, Kemp, loc. cit., p. 45, pi. ii, fig. 31. 
Six specimens, the largest a male 73 mm. in length, were obtained in company 
with typical scorpio. As in the case of the collection from the Chilka Lake,^ 
where both forms also occur, no specimen with intermediate characters is to be found. 
The variety immaculata has hitherto not been recorded east of the Bay of Bengal. 
Squilla nepa, Latreille (Bigelow). 
1913. Squilla nepa, Kemp, loc. cit., p. 60, pi. iv, fig. 49. 
Two Specimens were obtained, the largest a male 70 mm. in length. 5. nepa has 
not hitherto been reported from brackish water. 
Squilla interrupta, Kemp. 
1913. Squilla interrupta, Kemp, loc. cit., p. 72, pi. v, figs. 60-62. 
A number of young specimens were obtained^ the largest only 46 mm. in length. 
In very small individuals the tubercles on the upper edge of the carpus are represen- 
ted only by two obscure lobes. This species also was not previously known to inhabit 
brackish water. 
Squilla raphidea, Fabricius. 
1913. Squilla faphidea, Kemp, loc. cit., p. 88, pi. vii, fig. 77. 
Two specimens were obtained, a female 255 mm. in length and a male 200 mm. in 
length. The latter individual differs from the majority of large examples of the same 
sex, preserved in the Indian Museum, in the complete absence of the angular projec- 
tion on the external border of the dactylus of the raptorial claw. In the paper cited 
above attention is drawn to the existence of the same phenomenon in a male 190 mm. 
in length. 5. raphidea has not hitherto been recorded from brackish water. 
ADDENDUM. 
While this paper was in the press 1 received from Soochow, through the kindness of Prof. N. 
Gist Gee, some further specimens of Palaemonetes sinensis (see p. 272). The largest of these indivi- 
duals is 40 mm. in length, whereas none of those collected by Dr. Annandale exceed 25 mm. Some of 
the Soochow specimens are ovigerous, bearing eggs about 1*2 x 0-94 mm. in longer and shorter dia- 
meter.
