FISH. 



Melanic specimens of the Putia {Barbtis iicto). — The Putia is 

 a small Cyprinine fish very common in ponds thioughout India. 

 The normal coloration is given by Day {Faun. Ind., Fishes, i, p. 

 325) as " silvery, sometimes stained with red, a black spot on the 

 side of the tail before the base of the caudal fin and immediately 

 behind the anal ; a smaller one (frequently absent) at the commence- 

 ment of the lateral line. Fins often black, sometimes orange." A 

 number of specimens recently obtained from a tank at Rampur 

 Bhoolia in the Rajshahi district of Eastern Bengal, show a varying 

 tendency towards melanism. In some individuals this is barely 

 perceptible, but in some the edges of the lateral and the whole of the 

 ventral scales, the dorsal surface of the head and the fins (especially 

 the pelvic, anal and dorsal) are more or less densel}^ suffused with 

 black. This is less noticeable in the region between the anal fin 

 and the caudal spot, which is faintly ringed both in these and in 

 normal specimens with cream-colour. The region below the caudal 

 spot can be seen to be slightly paler than the rest of the bod}^ even 

 in normal individuals, if they are examined alive ; but its paleness 

 is more striking in melanic examples. In none of those from Raj- 

 shahi can the anterior spot be distinguished ; the fins of the paler 

 individuals are almost colourless. 



Day gives the number of horny rays in the dorsal fin as 8 ; it 

 is just as frequently 7.

 CRUSTACEA. 



Two Barnacles new to Indian seas. — The following Cirri- 

 pedes do not appear to have been recorded hitherto from the seas 

 of India : — 



Pcecilasma gracile, Hoek. 



Several specimens from the spines of an Irregular Echinoid 

 dredged by the Indian Marine Surve}^ off the extreme south of India 

 (Lat. 8° 37' N., Long. 75° 37' 30" E.) from a depth of between 224 

 and 283 fathoms. The species was originally obtained by the 

 ' Challenger ' off Australia from a depth of 410 fathoms. 



Pcecilasma eburneum, Hinds 



Several specimens from the spines of an Echinoid of the family 

 Cidaridge, dredged by the Indian Marine Survey in the Pers'an Gulf 

 from a depth of between 48 and 49 fathoms. The species was 

 described from New Guinea. The specimens here recorded, as well 

 as those of P. gracile, were attached to the spines surrounding the 

 mouth of the Echinoid on which they occurred.
