MARINE FISHES. 217 



Equula splendens, Crrv. 

 Numerous in Palk Bay, Stations XVIII. and XIX. 



Gazza equulseformis, Ruppell. 

 A single specimen, about G inches long, from Palk Bay, Station XVIII. The 

 other species of fishes taken at Station XVIII. in Palk Bay were Gazza equulaformis, 

 Equula splendens, Psettodes erumei, Trichonotus setigerus, Scicena maculafa, Cyno- 

 glossus arel, C. bengalensis, Pseudorhombus a?-sius and Caranx hippos. 



TKICHIUEID/E. 

 Trichiurus savala, Cuv. and Val. 



One specimen, 23 inches long, from Palk Strait. 



The first pair of teeth in the upper jaw are very large curved fangs, which are received 

 into depressions in the lover jaw, the remaining teeth in both jaws are much smaller 

 and are flattened from side to side, so as to form pointed, cutting instruments. 



SCLENID.E. 

 Sciasna diacanthus (Lack>ede). 

 One specimen, about 12 inches long, from Palk Strait. 



Sciaena maculata (Bl. Schn.). 

 One specimen, about 7 inches long, from Palk Bay. 



TEUTHIDID.E. 

 Teuthis orainin, Gunthkk. 

 A number of specimens from south of Cheval Paar, at Station XLVII. 



Note on the Limb Girdles of Teuthis oramin. 



The limb girdles in the genus Teuthis present several interesting jaeculiarities 

 which have not, so far as I am aware, been figured. Text-figure 2 shows the natural 

 relations of these structures in a specimen about 2 inches long. A faint line is 

 visible in the skin of the fish, extending from above the base of the pectoral fin to 

 the root of the anal. On dissection this is seen to be produced by a curved bony 

 bar, which is obviously the post-clavicle. Its upper extremity articulates with the 

 clavicle near the upper end of the latter. Its lower extremity is connected to the 

 anterior end of the 1st axonost by a strong fibrous bundle. The latter bone is very 

 stout, is strengthened by anterior and posterior ridges, and is grooved on its ventral 

 surface for the reception of the first two anal spines. Scapula and coracoid are quite 

 distinct, but are closely connected ; the former has a large fenestra ; there are four
