9. Clupea thrissa, L. is undoubtedly an ludo-Pacific species of Ojiis- 

 tJionema. The Carolina si)eciinens referred by Linua'iis to that species 

 were of the species Dorosoma cepedianum. Our Opisthonema must 

 therefore probably be called 0. oglina (Les.)- 



Trichiurus lepturus. L. 



Linn:^, Syst. Nat., eel. xii, 429. 



No. 1, Garden. Snake Fish. 



In the twelfth edition of the Systema Naturae there is no reference to 

 this Gardenian specimen of the Hair-tail, and no writing of Linne's is 

 on the reverse of the label. Garden's specimen is in bad condition; it 

 is about 780'""" long. 



Gadus tau, L. 



LiNNE, Syst. Nat., ed. xii, 439. 



No. 16, Garden. 



There are two specimens of this species, the larger of which is 160"™ 

 long. They represent the ordinary form of Batrachus tau. 



Echeneis naucrates, L. 



LiNNE, Syst. Nat., ed. xii, 446. 



No. 32, Garden. Sucking Fish. 



These specimens are not referred to by Linne, who evidently placed 

 them at once with his Echeneis naucrates, already described, and to 

 which he also refers Catesby's plate 26. These have 24 laminsB in the 

 disk. The larger one is 340""" in length to caudal base. 



Corypliaena psittacus, L. 



Li^N^Nifi, Syst. Nat., ed. xii, 448. 



The type of this species was labeled in Linne's own writing, and marked 

 No. 20 (evidently the No. 20 referred to, on page 313, Correspondence 

 with Linne by Garden, as a fish of suri^assing beauty) ; it is the species 

 which has long been known as Xyrichtliys vermicidatus. Linne's de- 

 scription agrees fully with this example, except in the count of the 

 dorsal, which for some unknown reason is 2^9 instead of 2^2? ^-s Linne 

 would have made it. All the other fin rays are correctly given. 



The length of the type to caudal base is 151"'"', and the characters 

 are as follows: D. IX, 12; A. Ill, 12; the last of the dorsal and anal 

 rays double; Y. 0; P. 11; C. 14; scales, 2 above, tubes about 24 in all. 



Lateral line interrupted under the tenth ray of dorsal. Accessory 

 line beginning on the median line under the end of upper lateral line, 

 and consisting of 5 short tubes. 



Height one-third of length to caudal base ; head one-fourth. 



Eye about equal to upper jaw, and placed about at top of head. 



The species must be called Xyrichthys psittacus, (L.). 



Dr. Glinther supposed CorypJuvna, psittacus, L., to be a Pseudoscams, 

 Cat. TV, 225. That Pseudoscarushixs received another name.
