Crustacea. 



Ocypoda macrocera, Milne-Edwards (see Alcock, Journ. Asiat. 

 Sac. Bengal, LXIX, II, p. 347) is by far the most striking crab 

 on the beach on account of its bright red colour, large 

 numbers and considerable size. 



Scopimera investigatoris , Alcock (see Kemp, Rec. Ind. Mus., 

 XVI, pp. 316, 317) burrows in the sand at about high tide- 

 mark, arranging its moderately large pellets beside a broad 

 and ver}^ definite straight pathway from its hole. 



Dotilla intermedia, de Man (see Kemp, Rec. Ind. Mus., XVI, 

 PP- 33I~333j fig- 10) occurs to some extent with Scopimera 

 but also extends a great deal further out. Where it burrows 

 in sand that is not too wet it brings up pellets, somewhat 

 smaller than those of Scopimera, and arranges them in 

 concentric arcs which may be completed to form either a 

 spiral or a series of concentric circles, with less definite 

 paths across them from the burrow to the outside. When 

 burrowing in wet mud it builds a sort of rampart round its 

 hole, which often closes over it as a small dome. Two 

 forms of male occur at Chandipore in this species (see Kemp, 



loc. cit., pp. 331-333, fig- 10)- 

 M acrophthalmus transversus, I,atreille (see Kemp, Rec. Ind. 

 Mus., XVI, p. 386) lives further out towards low water than 

 does Dotilla. It is usually common, but was very scarce in 

 1916. Its burrows are markedly oblique, not vertical as are 

 those of Ocypoda, Scopimera and Dotilla. 



Arachnid A. 



Limulus molluccanus, Latreille (see Pocock, Ann. Mag. Nat. 

 Hist., 7, IX, pp. 260-266, pi. v-vi ; and Annandale, Rec. 

 Ind. Mus, III, pp. 294-295), is moderately abundant, 



Insecta. 



Cicindela biramosa, Fabricius, is very abundant. 



Cicindela quadrilineata , Fabricius, is sometimes to be found 

 where the ground is muddy. In 1919 it was comparatively 

 abundant on muddy sand at the mouth of the Burhabalang 

 River, Both species are common seashore insects, living 

 near high-tide mark, but I am not aware that they have 

 been found so closely associated before. In Annandale and 

 Horn's Annotated lyist of Indian Museum Cicindelinae (Cal- 

 cutta, 1909) C. biramosa is recorded from various places 

 from N. Canara on the Malabar coast to Java, and C. 

 quadrilineata from Burma and Bengal to south of Madras ; 

 and the known range of the latter species is extended in 

 the '' Fauna of British India " to Sind and Baluchistan. 

 More recent observations both b^^ Dr. Annandale and 

 myself suggest that C. biramosa is the common seashore 

 species of the east and south-west coasts of the Indian 

 Peninsula, that C. quadrilineata holds this position on the
