Squilla oratoria var. perpensa, Kemp. [p. 70.] 

 A few specimens of no great size were brought in by the fishermen at Kilakarai, 



and a very youngle example, 21 mm. in length, was found among weeds near the 



shore. 



Squilla multicarinata, White, [p. 86.] 

 A magnificent example of this scarce and finely sculptured species, a male 



measuring 82 mm., was brought in by a fisherman during our stay at Kilakarai. 



The dusky patches noticed on the second and fifth abdominal somites are not visible 



in this specimen, but in every other respect it agrees precisely with the examples in 



the Indian Museum from Hongkong. 



Squilla multicarinata has not hitherto been recorded west of Burma. 



Pseudosquilla ciliata (Fabricius). [p. 96.] 

 A large male, 82 mm. in length, was brought to us by a fisherman at Kilakarai. 

 The specimen was bright olive green in life with the fringes of the antennal scale and 

 uropods crimson. 



Lysiosquilla acanthocarpus, Miers. [p. 120.] 



A living specimen of this uncommon species, a female 56 mm. in length, was 

 discovered at low water on the beach at Kilakarai. The spot where it was found was 

 one that we habitually passed, but though careful watch was kept no further speci- 

 mens were obtained. A dredge was shot several times a short distance from shore 

 and dragged to land, but this too proved unsuccessful. 



Placed in a shallow dish with a little water the specimen gave an interesting 

 demonstration of the ease with which the species of this genus can reverse their posi- 

 tion in a narrow burrow. When laid on its back it would rapidly assume a normal 

 posture by turning its anterior extremity upwards and backwards and creeping along 

 its own body. Such an action would be impossible in the case of more firmly seg- 

 mented species such as those of the genera Squilla, Pseudosquilla and Gonodactylus 

 and there can be little doubt that it is among the species of Lysiosquilla that the 

 highest degree of specialization for life in burrows is to be found. 



When picked up, the specimen attacked the fingers of its captor with both ends 

 of its body simultaneously, striking out vigorously with its raptorial claws and at the 

 same time endeavouring to make wounds with the spinous armature on its telson and 

 uropods. 



Its colour did not differ very much from that of specimens preserved for many 

 years in alcohol. The rostrum, eye-peduncles, and the basal segments of the anten- 

 nules and antennae were mottled with russet brown, black and pure white. The 

 proximal part of the antennal scale was white. The dark bands on the free thoracic 

 somites and abdomen were blackish grey, separated by ivory white. On the telson 

 the black colouring was much more intense than elsewhere and the three pale streaks 

 that invade the black patch proximally were pale lemon yellow. Seen from below 

 the animal was semi-transparent.
