The Squalus punctatus Mitch. (Traus. Lit. and Phil. Soc. 1, 484), 

 agrees well enough with the comraon ScoUodon terncnovcc, and was 

 probably founded on that species. It has, however, been identified 

 by Gill with Gareharias isodon M. & H., a species oi Aprionodon. This 

 species is known only from a specimen collected by Milbert — the local- 

 ity not stated; but as some other collections of Milbert were made 

 at I^ew York, this type of C. isodon has been assumed to be from that 

 locality. So far as we know, no American collector has ever obtained 

 a specimen of the species, and Gareharias isodon, or Aprionodon puncta- 

 tus, should be erased from our lists. 



It is not likely that, the tyi^e of ^^ ScoUodsn terraiiovtc'^ really came 

 from Newfoundland. It is a southern species, and is very abundant 

 along our South Atlantic and Gulf coasts. 



4. Sccliodon terras-novae (Rich.) Gill. P. 



Two young specimens obtained at Pensacola, where the si^ecies are 

 said to be common. 



SPHYRNID^. 



5. Sphyrna tiburo (L.) Kaf. — Shovel-nosed shark (Peusacola). P. 



Abundant at Pensacola. 



PRISTIDIDJE. 



6. Pristis pectinatus Latham. — Smc-Jish. G, 



Common. Tliere is thus far no evidence of the occurrence of Pristis 

 antiquornm in American waters, although the name occurs in several 

 lists of species. 



TEYGONID.E. 



7. Trygon sabina Le Sneur. — Sting-ray; Sting-a-ree. G. (31045). 



Generally common. Also seen in the markets of New Orleans, being 

 obtained in Lake Pontchartrain and Lake Borgne. 



SILUPvID^E. 



8. Arius felis (L.) J. & Q.—Sea cat-fish ; Blue cat. G. 



Very common on the sandy beaches. It is seldom brought into the 

 markets, and is eaten chiefly by the negroes. The specimens seen 

 belong to the form described by Baird «& Girard as Arius equestris. This 

 form agrees in dentition, character of bony i)lates, etc., fully with the 

 Arius fdis of the Atlantic coast. The barbels in specimens of equestris 

 examined are, however, somewhat longer, the maxillary barbel extend-
