places, about rotten trees. They do not breed until the last of 

 April. 



Elaps fuhiiis is rare. 



Coluber guttatus is more common. 



Psammophisflagelliformis equally so, although Holbrook speaks 

 of having seen but one or two specimens, and says that it is 

 quite rare in South Carolina. Heterodon niger^ pJatyrhinos and 

 scimus (?) are also common. All of these last breed in April. 

 Rana halecina is rather common, and Hylodes gryllus is here 

 what the Pickeringii is in New England. It exists in myriads, 

 and breeds as early as January. 



PJeihodon glutinosus is rare, and like the Salamanders hiber- 

 nates beneath wet logs, and goes into the water to breed in 

 April. 



Salamandra symmetrica is quite common. Its habits are like 

 those of the last. 



With regard to the geographical range of reptiles, Mr. 

 Ay res remarked, that Heterodon niger has been generally 

 considered a strictly southern species, not having been 

 found north of South Carolina by any naturalist previous to 

 himself. He had found a single specimen in East Hart- 

 ford, Conn. 



Dr. Storer said, that Cistudo Blandingii had not been 

 observed by naturalists north of South Carolina until he 

 saw a specimen in Bradford, Mass. 



Mr. H. R. Storer alluded to the circumstance, that a 

 specimen of Salamandra symmetrica, recently presented by 

 Dr. Durkee was obtained in Canada, north of Lake Onta- 

 rio. The great Lakes have usually seemed to constitute a 

 natural boundary to the distribution of species. 



Mr. Ayres stated some of the results of his investigations 

 among the Holothuridae of the coast of the United States, 

 as presented at previous meetings of the Society. 



Thirteen species have been described, included in eight genera. 

 Of these, three genera and eight species are believed to be new. 

 The following list gives, with the name of each species, the
