Corrections to No. IV {Limnophora and Anthomyia) of 

 " Notes on Oriental Diptera " {Rec. Ind. Mus., i, p. 381). — 

 My Limnophora himalayensis , described on p. 381 of the first 

 volume of these Records, is a Spilogaster , the arista being distinctly, 

 though rather shortl}^, plumose. The figures 3 and 3a in pi. xv 

 {loc. cit.) become incorrect, in consequence of the omission of this 

 character. 



A second error of mine occurs in the description of Anthomyia 

 bisetosa, Thorns., in which the arista is stated to be bare, whereas 

 it is shortl}^ pilose, as described by the author. Figures 4, aa, 5 

 and 5a become correspondingly incorrect. 



The new Palsearctic Catalogue confirms the synonymy of 

 Anthomyia lobalis, Thorns., with Limnophora tonitrui, Wied. 

 {Anthomyia id). Anthomyia iliac ata , Wlk. , is retained in that genus 



in the new Catalogue. .. ,. ,

CRUSTACEA. . : ■ - ■• 



A note on the Isopod genus TachcBa. — When lately describ- 

 ing Tachcea spongillicola , sp. nov., an Isopod found by Dr. Annan- 

 dale in the canals of a freshwater sponge at Calcutta {Journ. Linn. 

 Soc. London, vol. xxx, p. 39, 1907), I unfortunately omitted from 

 the list of known species of the same genus all mention of Tachcsa 

 lacustris, Max Weber, published in 1892 {Zool. Ergebn. einer Reise 

 in Niederl. Ost. Ind., vol. ii, p. 551). Professor Max Weber has 

 now very kindl}^ given me the opportunity of comparing his species 

 with my own, and agrees with me in thinking them distinct, though 

 closely related. His species has the seventh joint of the maxillipeds 

 distinct, and the sixth joint of the first gnathopods long and narrow. 

 It was taken in Sumatra, from the Lake of Singkarah, at a height 

 of 362 metres above the sea, where it lodged, together with Rocinela 

 typus, Milne Edwards, on the skin of various Cyprinoids.

The habits of the Amphipod Quadrivisio bengalensis. Stee- 

 ring. — This interesting species is very abundant in the brackish 

 ponds at Port Canning. An active swimmer, it shelters itself 

 during the cold weather among grass-roots overgrown with sponges 

 and amidst the filaments of green algse, while in summer it buries 

 itself in the mud at the bottom of the ponds, from which, how- 

 ever, it is ver}' easily aroused. 



As regards oviposition, which takes place in winter, it is gre- 

 garious, a favourite nursery for the eggs being the cavities in living 

 sponges [Spongilla alba, Carter), in which several individuals may 

 often be found keeping joint guard over a mass of small white eggs. 

 No nest is built.
