brittle material. The type specimen has a height of 18.5 mm. and a 

 width of 14.5 mm., with the ratio of I : .79. 



Locality. — A single very perfect valve was collected from the lime- 

 stone in the green shale member (number 5) in the " east " valley, 

 north of Three Forks. A somewhat smaller and less perfect specimen 

 was collected by Dr. Raymond in 1903, from near this same locality. 

 This type appears to be different from any figured species and so the 

 writer has placed it in a new species which is named in honor of Mr. 

 G. E. Hubbard, who found the specimen while aiding the writer in 

 his geological work near Three Forks.

A few specimens from the middle of member number 5, collected by 

 Dr. Raymond and the writer, were identified as Orbiculoidea sp. and 

 one or two of the best preserved specimens were identified as Orbicu- 

 loidea lodiensis Vanuxem, on their general agreement with the de- 

 scription and figures of the Nevadan form from the White Pine Shale 

 as noted by Dr. Walcott.

This form is apparently identical with the specimen figured by Dr. 

 Raymond from the red shale as Spirifer pinonensis. About sixty 

 specimens from the green shale and associated limestone were carefully 

 studied by the writer, and they show marked differences from S. pino- 

 nensis as figured and described by Mr. Meek. These differences are 

 as follows:
