Remarks. — This most interesting little creature is given by 

 Packard as ranging from' Massachusetts to Philadelphia, and 

 west to Ohio and Indiana. My description, as given above, is 

 based on six examples obtained in March, 1891, by Mr. J. S. 

 Witmer, Jr., at Paradise, in Lancaster county, Pennsylvania. 

 There are but few places in New Jersey where it has been ob- 

 served and recorded. The first was at Woodbury, and subse- 

 quently near Trenton, which latter will be mentioned below. 

 Outside New Jersey it has several times been seen in the Dela- 

 ware river valley in Pennsylvania. Mr. T. D. Keimi found it 

 in ditches above Bristol, in Bucks county, on April 12th, 1908,. 

 when it was fairly abundant. Several years previously Dr. J. 

 DeB. Abbott found it in pools in woodland a mile or so still 

 north of this place, where it was very common during ]\larch. 

 I also found it in this region March 25th, 1913. Mr. F. M. 

 Meyers found it very abundant in ''dry-land pond" near Bethle- 

 hem, in Northampton county. He sent me a specimen in March, 

 1913. I have also examined a number of examples from Long 

 Island, received from Gissler, though now very poorly pre- 

 served. Mr. W. T. Davis forwarded some examples he ob- 

 tained at Staten Island, N. Y., in March and April of 1897. 



Dr. Charles C. Abbott gives the following interesting account 

 of this species from near Trenton. "Ahimal life, in April, must 

 not be ignored. Many creatures that have been comparatively 

 inactive during the winter are now gradually assuming their 

 sumimier restlessness. Among the countless hundreds of objects 

 worthy of the rambler's attention, perhaps none are so beautiful 

 and full of interest as the fairy shrimps that throng the dark 

 waters of an upland sink-hole. This hollow in the field has a 

 foot or miore of water in it from: November to June, and during 

 the past winter it was frozen to the bottom until the ist of 

 April. A hard time, therefore, thought I, have these fairy
