of palm, carpus, and spot at distal end of merus. Telsonand back of carapace 
marked like rare shrimp. 
Sta. #21, Sept. 25, 1925* 
Went back to stream to see if I could find young Jamaicense, but though I 
looked at them all afternoon and in a.m. on 26th, couldn't make much out of 
lot. Got, however, 3 fair sized ? Jamaicense with black cross bars like one 
color noted under #18. And one striped brown one like we had been offering 
reward for, but not so red-brown. Bottled in vial. What can be the red ones 
have Just recently shed and the blue-greenish ones with yellow stripes are 
about ready to shed. I would say so because, in dying, red-brown ones get 
blue. 
olfersi great Jumper, can snap themselves almost a foot through the 
air, 6-8 high and foot away, and walk as well on—4 footed animals. 
Sta. #22, i$2£x Sept. 26, 1925- 
Went back to stream for oligochaetes. Luederwaldt has them all quite a 
number. Also, incidentally got seven shrimps, one cross barred Jamaicense like 
one under #18, smallest J amaicense I have seen which I know is that species. 
(But what are the long barred ones?) Two acanthurus , also smallest I think 
so far. Rost, and red vert. stripes on carapace 
definitely identify it. Also an Atya with light stripe 
* down middle. And 3 characteristically speckled olfersii 
i (J 
with dark cross bands on hinder margins of first 3 abd. 
somites; darkest and most conspicuous band on hinder 
margin of 3rd with characteristic clear transversely rectangular area in front 
of it.
