rested against the wall of the yard in which it was kept. It did not 

 ramble about, nor care much for water, but when put in a large tub 

 very dexterously pulled itself up by the hooked bill, until the claws 

 got on the edge. When handled, it bit severely." 



The specimen now belongs to Mr. W. D. King, of Sudburjs to 

 whom I am indebted for the opportunity of examining it, and also of 

 exhibiting it here. It accords well with Temminck's description of 

 the adult bird. 



Fishes. 



The first to be described in this class is a new genus of the family 

 T(cnioidee, for which I propose the name of Echiodon. It is founded 

 upon a specimen obtained on the coast of the county of Antrim, by 

 Dr. J. L. Drummond, in June 1836. 



Echiodon. 



Head oval; body much elongated, compressed, narrow, lanceolate; 

 snout moderately long ; mouth cleft obliquely, both jaws terminated 

 by large cylindrical teeth ; no ventral fins, nor scales instead ; fin- 

 rays all soft ; dorsal and anal fins continued throughout almost 

 the entire length ; branchiostegous membrane with seven rays. 



Considered relatively to the other Tanioidea; it agrees with Tri' 

 chiurus and Stylephorus, in wanting ventral fins, but not in any 

 other generic character ; from the head posteriorly it approaches 

 most nearly to Cepola, but in the form of the head and in dentition 

 differs remarkably from all the other genera. 



* Echiodon Driimmondii. Length 1 1 inches, depth 6 lines, breadth 

 3 lines, head one-ninth of the whole length, eye occupying the en- 

 tire upper half of head, teeth numerous and small, except two, which 

 are large and fang-like at each side the extremity of the upper jaw, 

 and one long cylindrical tooth terminating the lower jaw on each 

 side ; upper jaw the longer ; dorsal, anal, and caudal fins united ; 

 body without scales (?) ; lateral line inconspicuous; vent \\ inch 

 from point of lower jaw ; vertebrae 98.

* CrenUahrus microstoma. Couch MS. Small-mouthed Wrasse. 

 In June 1836, Dr. Drummond found a Crenilabrus, on the beach at 

 Cairnlough, county of Antrim, which he liberally handed over to me, 

 and appearing to be a new species, I at once drew up a detailed 

 description of it. I now find that the same Wrasse has been met 

 with in Cornwall by Mr. Couch, who likewise considered it as new 

 and sent two specimens to Mr. Yarrell, under the appropriate name 

 of Cren. microstoma, a term, though unpublished, which I consider 

 it but fair to adopt, as Mr. Couch had the priority in obtaining the 

 species. 



My specimen is about 3 inches long and moderately deep in pro- 

 portion, its depth being to its length as 1 to 3-^. Its most prominent 

 characters are, — mouth small, jaws equal, teeth few in number and
