PROCEEDINGS OF THE NATIONAL MUSEUM. 377 



This revision is based: 



(1) On a collection made by Prof. Eigenmann during a three years' 

 stay in California. Many of the species were here examined in hirge 

 numbers as they were brought to the markets. Collections were made 

 at San Diego, Cortes Bank, Monterey, and San Francisco. A nearly 

 complete series of these were presented to the Kational Museum. 



(2) On many of the specimens collected by Jordan and Gilbert, 

 which now belong to the ]S^atioiuil Museum and to the Indiana Uni- 

 versity. 



(3) A series of skulls and skeletons belonging to Mrs. Eigenmaun's 

 collection formed the basis for the classification into genera. 



We are indebted to Dr. Cf. Brown Goode for the use of species 

 belonging to the JSTational Museum and not otherwise accessible to us. 



To Messrs. Gilbert and Test we are indebted for examinations of 

 otherwise inaccessible specimens, and to Messrs. Gill and Jordan for 

 suggestions and criticisms. 



HISTORICAL NOTK ON THE VIVIPAROUS Gi^ENERA. 



The species of Schasfodes, SehastichtJiys, etc., Avere originally included 

 in the long known genus Sebastes. Dr. Gill first distinguished between 

 genera in the following historical sequence: 



1. Sehdstodes, Gill, Proc. Pliila. Acad. Sci., 1861, p. 165 (Sebasies paucispinis, Ayrks). 



2. Sehasiichthyfi, Gill, /. c. 1862, pp. 278, 329 (*S^. nigrociuctus, Ayres, type ; S. nebuJosus, 



Ayi!ES, S. auricnJaliis, Gikakd, S. occUatus, Cuviek, S. hclvo inacii I atii s, AYims, S. 

 meJanops, Gikai!D, aud yS. rosaceun, Aykes. 



3. Sebdalosovuis, Gill, /. e. 1864, pp. 59, 117 (S. miia)io2)8, Girakd), to include also 



Sebasfosoinus pinuitjcr, Gill. 



4. Sebastomus, Gill, /. c. 1864, iip.59, 147 (S. rosaceus, Gikakd). 



In the last paper quoted. Dr. Gill says: 



lu conclusion, the genus Sebastlchihys includes at least three genera. The Sehas- 

 tlchthys nif/rocinctiis is somewhat I'elated to Scorpii'na, and is distinguished by ele- 

 vated, serrated coronal [parietal] crests. Other California species represented by 

 the Sebasfes meJunops, seen by me, differ so much that they may be separated and 

 combined for the present under a genus Scbastosomus, of which the Sebasfes meJanops 

 of Ayres may be taken as the type. Still others, distinguished by the texture of 

 the bones of the skull, armed orbital ridges, prefrontals, etc., and represented by 

 Sebastes rosaceus, Girard, may be named Sebastomus. 



In 1880 Jordan and Gilbert* retained Sehastodes as a distinct genus, 

 but united all the other known species under the name iScbastichthys, 

 retaining Sebastosomus as a subgenus. 



These genera, Scbastodes, Sebastichthys, Sehastosomus, iSehasfonius, 

 were again united by Jordan and Gilbert f in 1882, under the generic 

 name Sebastodes, with the remark, "the species differ greatly in form 

 of armature, but the genera based. on these differences intergrade too 

 closely to be worthy of retention."
