In nearly all cases I have found this snail feeding on Jack-fruit (Artovarpus 
integrifolia) which had been putrified to a pulp, but on two or three occasions I 
found it greedily devouring a fungus like growth which occurs frequently on 
rotten logs but the name of which I am ignorant of.

No. XXV.—BUTTERFLY FEEDING ON EXCRETA. 
With reference to a recent note in the Journal of a butterfly drinking its own 
excreta, I send you herewith for identification a small butterfly which is at 
present common in my verandah at Dharmsala (4,000 feet). This morning I 
vatched one of them which had settled on the floor of the verandah ; it kept on 
bending its abdomen forward and depositing a drop of moisture which it then 
leaning backwards drank up with its proboscis. This was repeated several times,

No. XXVI.—THE BLACK ROCK SCORPION (PALAMNGUS 
SWAMMERDAMI). 
On 22nd July 1921, about 7 a.m., my pankah boy informed me that he had seen 
an animal go into some water standing in a brick drain into which my bath emp- 
tied. He told me that it was a scorpion and I did not believe him, never having 
heard of a scorpion voluntarily entering water. However, he stuck to it and I 
went to see. After taking out some broken brick the tail of a scorpion appeared 
and he was duly captured unharmed. I decided to see if he could really stand 
water for any time and put him into an enamelled jug three parts full. He, or 
rather she, displayed no anxiety and assumed the usual sparring attitude but 
presently relaxed and stayed quiet. Presently I scraped my foot slightly on 
the concrete floor and she immediately sprang to the defensive attitude. No 
part of me was touching the table or jug and the sound must have reached her 
through table and water. She responded to about 3 scrapes and then gave it up. 
After sitting quiet for about a quarter of an hour from the time of immersion 
she set to work quietly to explore her prison and to try and get out. She tried 
walking up the sides but they were too steep and smooth. Then with tail 
braced across the jug she worked up the opposite side with front legs and chelz 
until the jug by reason of its bulge became too wide for her to span. In doing 
this, when at greatest stretch, she bore against the side of the jug with the 
point of her sting so as to get the advantage of the length of vesicle. After 
several attempts this was given up and she tried bracing herself round the 
inside curve of the jug and working up sideways. At this she succeeded so 
well as to get the tarsus joints of top side out of water, but the overhang of 
the side defeated her and she slipped back. She tried this 3 times and then 
resigned herself to fate and sat quietly at the bottom. I had to go to office
