122 FISHES FROM GUAYMAS EVERMANN AND JENKINS. 



and Central America, inclnding the Gulf of California and the Bay of 

 Guaymas, made various collections of fishes. 



These have been studied by Professors Jordan and Gilbert (Proc. 

 U. S. Nat. Mus. 1881, p. 225). 



In 1880-'8l, Prof. Charles H. Gilbert spent ten weeks collecting fishes 

 at Mazatlau, a point which may be considered as being at the mouth 

 of the Gulf of California. During this time he obtained a large and 

 very important collection. This collection was made for the U. S. Na- 

 tional Museum and served .is the basis for many papers by Professors 

 Jordan and Gilbert which have appeared in the Proceedings of the LT S. 

 National Museum and in the Bulletins of the U. S. Fish Commission. 

 The first of these papers announced that one hundred and seventy 

 species were obtained and gave descriptions of thirty-three new species. 



Mr. W. N. Lockington has at various times given accounts of fishes 

 from the Gulf of California, some of which he described as new. 



In the Proceedings of the U. S. National Museum 1882, p. 378, Pro- 

 fessors Jordan and Gilbert give an account of a collection of fourteen 

 species made by Mr. L. Belding near Cape San Lucas. 



In the Proceedings of the U. S. National Museum 1884, Dr. Jordan 

 published an account of a small collection of four species made by Mr. 

 H. F. Emeric at Guaymas. One of these, Gohiosoma histrio, was de- 

 scribed as new. 



Besides these collections, there have been described at various times 

 from points in or near the Gulf of California, a number of species by 

 others, especially by Dr. Giinther and by Dr. Steindachner, the latter 

 having at one time visited the west coast of North America with 

 Agassiz on the Hassler expedition. 



Nearly all the species heretofore reported from the Gulf of California 

 have been from points south of Guaymas. 



Guaymas is situated on the Bay of Guaymas, Gulf of California, in 

 latitude 28° north and longitude 34° west, a position on the west coast 

 of iSonora, Mexico, about opposite the middle portion of the peninsula 

 of Lower California. 



The climate is very dry, there being at most but very few light 

 showers at any time. 



The bay is surrounded by mountains wholly of volcanic origin. The 

 coast line is an almost unbroken wall of rough, sharp-outlined rock 

 whi(;h the sea has in many places undermined into overhanging diti's 

 or caves. This wall, always high, sometimes rises into immense preci- 

 pices. 



There are but few places in the region of the bay where the seine 

 could be used to any advantage, and these had to be prepared by le- 

 moving many rocks. 



We were fortunate enough in being able to secure the aid of a French 

 fisherman, Mr. Theodore Canevet, who, being a man of intelligence, was 

 able to render us great aid in many ways. He was well informed as to
