It is not, liowever, the Scomber clirijsurus, ed. xii, 494, but it is ^he 

 Caranx Mppus of Jordan & Gilbert, Bull. 16, U. S. National Museum, 

 pages 437, 438, and agrees, except in tlie count of the anal, with Scomber 

 hippos, Linne, ed. xii, 494. 



The specimen is 220™" long to end of scutes, and has the followiug 

 characters : 



D. VIII, i, 20; A. II, i, 16; scutes 31. 



Opercular spot large ; breast naked, except a small patch in front of 

 ventral ; curved portion of lateral line as loug as the head. Third dorsal 

 spine a little more than one-third length of head. Eye one-fourth as 

 long as head ; head one- third of total to origin of rudimentary caudal 

 rays; maxilla one- third height of body ; mandible almost one-half length 

 of head. 



Scomber chrysurus, L. 



Linne, Syst. Nat., ed. xii, 494. 



This species is represented by four type specimens, ranging in length 

 from 95 to 150'""' to caudal base. 



There are two spines in front of and somewhat remote from the anal. 



D. VIII, i, 28 ; A. II, I, 27. 



The species is Chloroscombrus chrysurus. 



Trigla evolans, L. 



LiNNi^, Syst. Nat., ed. xii, 498. 



No. 21, Garden. 



The type of Trigla evolans is 90™™ long to base of caudal, and has 

 the following characters : 



D. X., 12; A. 12. There seem to be about fifty tubes in the lateral 

 line (sixty or more rows of scales). 



The length of the head is contained about 21 times in the total with- 

 out caudal. The eye is f as long as the head. There is no trace of a 

 furrow behind the eyes, and there are no dark lines at present along 

 the sides. The spines of the head do not appear nearly as much de- 

 veloped as in young P. tribulus. The spine at the angle of the preop- 

 erculum is not quite so long as the eye, and has a small spine at its 

 base. The opercular spine measuring back to the begiuniug of the ridge 

 is about as long as the orbit. The length of the maxilla is ^ of the total 

 without caudal. The pectoral reaches to the sixth anal ray. 



Cobitis heteroclitus, L. 



Linn£, Syst. -Nat., ed. xii, 500. 



No. 11, Garden. "Anonymos."' 



See page 305, volume i, Smith's Correspondence of Linne. The editor 

 of this volume has evidently been misled by the common name " mud- 

 fish," in referring number eleven to Amia calva, which was number 4 of a 

 later lot. (See page 312.) 



The above example was apparently the type of Linne's description of 

 Cobitis heteroclitus. In the annotated copy of edition xii, Linne wrote
