Nilghai, Boselaphus tragocamelus . In S. Chanda, in 1911, on 13th May, 

 I saw a BuU come and drink at a tank just after dawn. At one village 

 I was shewn a tank where " Nila " or " Nil," as the villagers called them, 

 used to drink at about 6 p.m., but I never saw any there, and I was also 

 told that the " Nil " did not drink regularly. On the night of 23rd May, 

 at the tank of another village I watched two Bulls drinking within a few 

 yards of me at about 8-30. I have never seen the Does drinking : and from 

 all accounts the Nilghai of the jungle is not a heavy or regular drinker. 



Four-horned Antelope, Tetracerus quadricornis. I have come across these 

 little animals drinking at tanks in S. Ohanda any number of times. They 

 do not drink at night and have no fixed drinking hours by day, as I have 

 seen them coming to water at any time between dawn and sunset. I will 

 quote a few instances from S. Chanda, May 1911 : — 



5th May 1911, when in camp by a roadside tank : watched a Doe 

 drinking on the far side, through my glasses about 4-30 p.m. 



Next day several came down singly and in pairs between 9 and 12 in 

 the morning. 



12th May, came on 4 Does drinking at a village tank at 8-30 in the morn- 

 ing and got within 30 yards of them. During the next ten days saw them, 

 both Bucks and Does, drinking at this tank at all hours between 8 a. m. 

 and 4 p. m. ; in one instance a very fine Buck came down. 



12th — 23rd May while in camp by another tank, a party of three, a Buck 

 and 2 Does, came twice daily at about 9 a.m., and 3 p.m., and drank not 

 more than 80 yards from my tent : odd ones used to wander down to this 

 tank and drink at all hours of the day and my servants used to call my 

 attention to them, when I used to watch them with my glasses. 



23rd and 24th May. At a tank by a different camp I saw some small 

 parties drinking about midday and others late in the afternoon. I could 

 quote many more instances but these should suffice. 



Chinkara, Gazella bennetti. I will not repeat my notes about these animals : 

 nor will I attempt to assert that these Gazelles cannot live without water : 

 for I am perfectly convinced that quite 80 per cent, or more of these Gazel- 

 les roam in such places where they cannot get any water. Any moisture 

 that they then require may possibly be obtained periodically from their 

 food plants. But on the other hand, from what I have seen on three 

 occasions in Chanda, I am quite certain that the " Chink " does drink 

 water when it is plentiful in its habitat, and in such cases may even get 

 into a regular habit of coming to drink. 



Langur, Presbytis entellus. Seemed to drink when they wanted it : but 

 usually once a day. • I saw them drinking at various hours in the day. 

 They drink like Deer and cattle with their mouths down to the water and 

 do not lap like Canines or Felines. 



Pea Fowl, Pavo cristatus. Used to drink every evening just before dusk : 

 sometimes a few came out in the early morning. 



Green Pigeon, Crocopus chlorog aster. Used to drink at dawn and 

 occasionally in the evening about 4-30 or 6 p.m. 



Dera Ismail Khak, C. R. S. PITMAN, 



September 1912. 27th Punjabis. 



No. X.— THE NUMBER OF TAIL FEATHERS IN THE 

 GENUS CRYPSIRHINA. 



In the Avifauna of British India, one of the characteristics of the Cor- 

 vidse mentioned is the possession of twelve rectrices or tail feathers, and no 

 mention is made of any exception among any of the sub-families or genera.
