The resignation of Dr. C. J. Cleburne, U. S. N., as a member of the 

 Committee on Conchology, on account of absence on official duty, was 

 read and accepted. 



Permission having been obtained, Mr. Cope presented, on behalf of Mr. H. 

 C. Wood, Jr., a large specimen (length 40 in.) of the iguana of Andros Island, 

 one of the Bahamas. The animal had been mentioned by Catesby in his history 

 of Carolina and the Bahamas, but had not apparently been noticed by any sub- 

 sequent naturalist. The species was congeneric with, and allied to Cyclura 

 lophomaffjsse, of Jamaica, but the crest was very low, and extensively in- 

 terrupted over the shoulder and loins. The head plates differed from 

 those of the Cuban species, C. nubila and M a c L e a y i. The color of the 

 animal was black, with yellowish reticulations. The mastoid and gulo-rictal 

 tubercles, dorsal crest, caudal whorls, middle of the abdomen, and antibra- 

 chium, were pink. The head and jaws light pinkish brown. Mr. Cope stated 

 that a further account would shortly be given of the animal, under the name 

 of Cyclura baeolopha. The Academy Museum possesses, also, a fine in- 

 dividual of C. pectinata Wtej. from Honduras, presented by Dr. J. L. 

 Le Conte. 



Mr. Cope presented a specimen of Amblystoma Jeffersonianum Baird, 

 found near Thorndale, Chester Co., Pa. The species was very rare, having to 

 the speaker's knowledge been previously only found in Western Pennsylvania 

 and near Philadelphia. Dr. Hallowell was in error in regarding this species as 

 identical with the i n g e n s of Green, hence the mistake which the speaker 

 had formerly fallen into,* of quoting Tschudi's Xiphonura as applicable to the 

 same type as Gray's Heterotriton. 



Another specimen of an Amblystoma on the table, from Ohio, Mr. Cope ob- 

 served had been regarded t as belonging to the Sal. porphyriticaof Green . 

 Prof. Baird having shown that that species is tbe S. salmoneaof Storer, or 

 Pseudotriton salmoneus Baird, he would call the Ohio species Amblys- 

 toma microstomum.
