of five dorsal spines, and by certain minor differences in 

 the proportions of head and body, the size of the eye, and 

 the number of fin rays. 



In the ichthyological collections of Stanford University, 

 there are now some seventy-five young specimens of a 

 Clevelmidia collected at the mouth of Butano Creek, near 

 Pescadero, San Mateo County, California, by Mr. James M. 

 Hyde. They are within the range therefore of Clevelandia 

 roscB and near the type locality of the species. These speci- 

 mens have been compared with typical ios from Puget 

 Sound (the Seattle specimens already referred to) and with 

 a specimen of roscB from San Diego, kindly furnished for 

 that purpose by Dr. Eigenmann. No doubt can remain 

 that the two species are not distinguishable and must be 

 united under the oldest name. 



The type of C. ros(B is described as having four dorsal 

 spines. From the following table it appears that five is 

 the usual number, varying rarely to four. There are 

 usually sixteen dorsal rays, varying rarely to seventeen, and 

 fifteen anal rays, varying to sixteen. The statement by 

 Jordan and Starks (see synonomy) that the Seattle speci- 

 mens had fourteen anal rays is erroneous. In their accom- 

 panying illustration the number is correctly represented as 

 sixteen.
