The history and status of this species, which has been considered one fortui- 

 tously introduced is discussed among the remarks upon L. inoptatus, sp. nov. 

 from Haiti.

The types of this species were six specimens now in a very bad state of 

 preservation which were sent to the U. S. national museum from the region of 

 Guantanamo, Cuba, by Mr. Charles Wright, a very accomplished botanical and 

 zoological collector. I can not learn that the species has been taken since until 

 1912. Gundlach in all his trips over the island never collected it. I found it 

 at two neighbouring stations. One a seborucal near Colonia Limones, another 

 in an area of dense woods near Colonia Guabairo, both on the Soledad planta- 

 tion near Cienfuegos. 



The seborucal, as any densely wooded area upon a region of limestone rocks 

 is called, was hke an island in a sea of cane fields and the jungle was so dense and 

 thorny that it could only be entered by following up the bed of a small stream. 

 In company with Mr. R. M. Grey I found one of these tiny frogs under a stone 

 on the bank of the stream. Another was seen but not secured. Greatly dis- 

 appointed, for I reaUzed at once the identity and interest of the find, we revisited 

 the locality several times but were unsuccessful. 



Some days later while enjoying the hospitality of Captain Beal of Guabairo, 

 Mrs. Barbour and I were collecting along an old wood trail in the early morning 

 when we came to a stony place in the road, evidently a sort of stream bed flowed 

 over only during a heavy rain. By diligent searching under these stones we 

 obtained a good series all of exactly the same minute size. The species is an 

 extremely active and delicate one and to obtain uninjured specimens means 

 quick and accurate work with the forceps. 



The colors in life are as Cope has described them and he was certainly 

 correct in adding that " This is perhaps the smallest frog known, and is a very 

 prettily marked one." 



Believing it probable that this species might in reality not be a true Phyllo- 

 bates at all I cleared an entire specimen with chemical reagents and was thus 

 able to study the sternum critically. The examination showed that the species 

 was in every way a typical Phyllobates.
