is greatest, is 69°"8. We Lave no particulars, "beyond the oc- 

 currence of occasional showers, to account for the large number 

 of species Avhich is found in May. The fact that the climate is, 

 on the whole, more temperate than that of some other islands in 

 the same latitudes would lead us to expect the presence of a 

 comparatively large number of European species, or those which 

 are found in tlie more northern United States or British North 

 America, and may account for the fact that so small a propor- 

 tion of species should be identical with those from neighbouring 

 islands. We do not expect the same rule to prevail as to the 

 character of an insular mycology as in an insular flora; and it 

 is possible that the disproportion might vanish if the other West- 

 Indian islands had been as diligently explored. 



Our observations are founded, indeed, on only a little more 

 than half the species, no dates being given with the others. One 

 species, Agariciis bomhyeinns, a species which occurs both In Eu- 

 rope and America, is marked as coming from Valparaiso, but 

 whether from a district iu Cuba so called, or not, we have no 

 information. 



Perhaps the most interesting species are those which occur in 

 the genera Craterellus and Lascliia^ the latter genus especially 

 yielding several new forms. We have found it necessary to 

 propose a new genus, Grammotliele^ for a group of curious but 

 rather obscure species, while Micheneray with which w^e have 

 long been acquainted as occurring in the United States, is pecu- 

 liarly interesting in point of structure. HymenoclK^te veJuti- 

 ceps is an entirely new form in the genus, Avith no immediate 

 ally. 



AVe reserve a general comparison with the mycology of other 

 countries till we have examined the remainder of the collections, 

 ■which, though extensive, do not amount to the same number as 



r 



those now laid before the Society, nor can they boast of the great 

 prevalence of curious forma which characterized the analogous 

 part of the collections made by Lepricur In Cayenne. 



The habitats appended to species already described are taken 

 . from specimens In our herbaria or such as have passed through 

 our hands, but do not profess to be at all perfect.
