dotted; its middle third jet black, margined with white. Pectorals 

 and ventrals hyaline, colorless or yellowish, sparingly black dotted aud 

 white edged. A large, conspicuous, metallic blue-black spot on the 

 opercle; top of bead blackish; belly white or yellowish; chin and 

 throat white, sometimes punctate. 



Young lighter, showing the reticulations, but the other markings 

 faint or undeveloped. 



The types of this species were obtained by a Chinaman when digging 

 for "crawfish" in the mud flats between Roseville and La Plava. 



This species differs greatly from the known species of Lepidogobiw. 

 It is most nearly related to L. newberrii, belonging to the subgenus 

 Eucyclogobius. Among other differences are the number of fin rays and 

 the rounded caudal fin. 



Some specimens, which may be the young of Qillichthys mirabilis, 

 were associated with this species. The eyes are smaller than in L. 

 •gllberti, the mouth larger, the maxillary exteuding considerably beyond 

 the orbit. The abdominal area is slightly longer, the ventral fins much 

 shorter. The number of fin rays agree with those of gilberti. In speci- 

 mens .0I5 m long there is a median series of black spots on the sides, 

 and a series of less distinct blotches along the middle dorsal line. The 

 cranial markings are as in the adult of Gillichthys mirabilis. 



We have dedicated this species to Mr. C. H. Gilbert, Associate Pro- 

 fessor of Zoology, Indiana University. 



Ophiodon elongatus Girard. 



This species, known from Monterey and northward, has frequently 

 been caught off San Diego this winter. 



Cebedichthys violaceus Girard. 



This blenny has been recorded from San Francisco to Point Concep- 

 cion. In May, 1886, Mr. C. R. Orcutt collected a single specimen at 

 San Quentin, Lower California, 200 miles south of San Diego. 



Sebastichthys chlorostictus Jordan and Gilbert. 



A large number of this species were caught off San Diego February 

 '26. Like the preceding species, it has not before been recorded south 

 of Monterey. 



Sebastichthys vexillaris Jordan and Gilbert. 



The species of Sebastichthys evidently do not bring forth their young 

 at any particular time. Only oue of the many specimens of S. vexillaris 

 examined has been found with young. The ovary is double, as in Sc- 

 bastes marinus, but contains a much greater number of young. The in- 

 ternal structure of the ovary agrees with the description of the ovary
