plentiful on the lower part of the Island, Mosquitoes were very 

 troublesome. At the time he last visited Rock Island (July 3d), 

 the small shelled crustaceans had almost entirely disappeared. 

 He had gathered a lot of turtle eggs which he was going to try 

 to hatch. 



Several weeks ago August Stuhr brought to the Academy an 

 immense bull frog {Rana Cateshiana^ Schaw.) measuring 

 when stretched out, fourteen inches from the head to the tip of 

 the feet. To-day he presented a specimen of fishing duck 

 ( Mergus Merganser). 



A cigar-box containing four horned toads, alive and in good 

 condition, was received by mail a few days ago, liaving been 

 sent from San Bernardino, Cal., by Mrs, Dr. C. C. Parry. 

 They are of the species Phrynosoma coronatum, Blain. 



Mr. Putnam stated that he had lately examined the specimens 

 of Phrynosoma contained in the collection. They can all prob- 

 ably be referred to the following three species : 



Phrynosoma coronatum Blain. Four living specimens in different 

 stages of growth, recently received from Mrs. Parry, San Bernardino, 

 Cal. This is by far the most handsome species of the genus we have 

 .seen. 



Phrynosoma cornutiun Gray. Two living specimens lately received 

 from Texas (from Mrs. Col. Mandeville and Mr. Martin), and one speci- 

 men in alcoliol. 



Phrynosoma douglasii Gray. This species seems very generally dis- 

 tributed on the high table lands of the Rocky Mountains. I have ob- 

 served it in greater or less abundance in different parts of Colorado, 

 Wyoming and Utah, though it seems more plentiful in the sage brush 

 regions, and was not noticed in the mountains. In the collection of 

 the Academy there is a hue series of this species in all stages of growth, 

 collected at Spring L^ike Villa, Utah, last summer. There are also a 

 mniiber of specimens from Denver and Valmont, Col., and from the 

 neighborhood of i;^uth Pass, Wyoming. 



Mr. J. G. Haupt reported that he had made collections of 

 plants lately along the river bank to Gilbert, and for some dis- 

 tance up Duck Creek ; in various localities to the west of the 

 city ; and to a distance of four miles south of Rock Island. He 

 found a rare cliff-l)rake (Pelloea atropivrpurea) on rocks along 

 the river. Cystopterls fragilis is another new species collected 

 in the same locality. Pond lilies {Nuphar advena) were found
