Sebastodes paucispinis Gill. 

 One specimen is in the collection. 



Family COTTOID^E Girard. 



Subfamily COTTIISLE. 



Aspidocottus bison Girard. 



Three small specimens. 



Artedius notospilotus Girard. 



Three small specimens of this species are also in the collection. The spe- 

 cies undergoes so considerable a change with age, especially in the armature 

 of the head, that it might readily be the cause of a multiplication of nominal 

 species. 



Family GOBIOIBJE. 



Subfamily GOBIINiE. 



Lepidogobius gracilis Gill. 



Two specimens in the collection. 



The Gobius newberrii of Girard is the type of another genus, to which the 

 name of Eucyclogobius may be given ; it is distinguished from Lepidogobius 

 by the naked head, the oblong and equal second dorsal and anal fins, &c. 



Family BLENNIOID^. 



Subfamily CEBEDICHTHYIN^E Gill. 



Cebedichthys violaceus Girard. 

 A fine specimen is in the collection. 



Subfamily CENTIIONOTIN^E Gill. 



Apodichthys virescens Ayres. 

 Three specimens. 



The Apodichthys flavidus of Girard, as originally based, may possibly be dis- 

 tinct from A. virescens Ayres, but there can be no doubt that one of the spe- 

 cimens sent to the Smithsonian Institution by Ayres under the name of A. 

 virescens and referred by Girard to A. flavidus, truly belongs to the former 

 species. 



Apodichthys sanguineus Gill.* 



This species resembles Apodichthys virescens, but is of a beautiful intense 

 red color, minutely punctulated with darker ; the dorsal and anal fins have 

 the margins rather darker and with a yellow dot generally in front of the tip 

 of each fourth to sixth ray, and more distinct on the anal. A dark purple 

 line under the eye is behind the upper jaw, but there is none above. 



D. XCIIL XCV. A. I. 40. 



* A specimen of Apodichthys which appears to represent another species of ihe genus 

 was obtained by the naturalist of the Northwestern Boundary Commission. It is 

 ihirteen inches long and rather discolored, but does not exhibit any trace whatever of 

 the characteristic line behind the upper jaw and below the eye. The anal spine is much 

 shorter and transversely cleft at the tip ; the latter is probably abnormal. I have deferred 

 a description, hoping to have the validity of the species confirmed by other specimens, 

 and am very reluctant to name it from the single one in the collection, but as this notice 

 may call attention to it, I have finally resolved to publish. The species may be called 

 A.inornatus. The radial formula is D. XC. A. I. 38. C. 23. P. 2. 11. 1. In pro- 

 portions it does not essentially differ from A. virescens or A. flavidus. The eye is, per- 

 haps, smaller and the body higher. The color is brownish, with a dark spot or blotch 

 on the back at the base of every fourth or fifth spine.
