It would appear that Sinaloa is the northernmost area reached 

 on the west coast of Mexico by many of the tropical forms. 

 Collections from Sonora, the Gulf of California and Baja Cali- 

 fornia recently examined, did not include any of the nineteen 

 such forms indicated by an asterisk in the above list. 



Excluding the forms carried by commerce and those havinfj; 

 a distribution extending both northward and southward, we 

 find that, in the present list, only five species previously known 

 only fiom north of Sinaloa or related to species there found.
