ADDITIONS TO FAUNA OF SAN DIEGO. II 



The diagnosis of the genus Clevelamiia may be aug- 

 mented with the statement that the skull is convex in 

 transverse profile w^ithout a trace of a median ridge. 

 Jenkins and Evermann, in an apparently hastily prepared 

 paper (Proc. U. S. Nat. Mus. 1888, 150), considered 

 Clevelaiidia\d.Qw\\z?\ with GillichtJiys . 



10. Lepidogobius (or gen. nov. ) y-cauda (Jenkins & Ever- 

 mann) . 



Gillichiys y-cauda, J. & E. Proc. U. S. Nat. Mus. 1888, 

 147 (Guaymas) 



This species has been recorded from Guaymas only. 

 It is also found in San Diego Bay, nearer low water 

 mark than C. loiigipiunis, and was considered a new spe- 

 cies by us. Dr. Gilbert has examined some of the typ- 

 ical specimens, and informs us that they have the dermal 

 shoulder flaps of Lepidogobius and bands of teeth instead 

 of single series as stated by Jenkins & Evermann. A 

 comparison of the skulls of this species, and of Lepidogo- 

 bius lepidus, is necessarv to determine its generic posi- 

 tion. It greatly resembles that of GillichtJiys. 



SCORP.^NID^. 



The members of this familv. or at least of the genus 

 Scbastodcs, seem to live at definite depths and on bot- 

 tom peculiar to each species or group of species. This 

 does not imply that their distribution is narrowly limited, 

 but that a given species may be found or not at any point 

 within the limits of its habitat, as the pecuharities of the 

 bottom at a given depth are fitted for it or not. To this 

 cause is to be attributed, in part, the fact that so many 

 northern forms have but lately been added to the fauna 

 of San Diego, and that a given species may be caught for 

 several days in succession, and then not appear again for
