the longest, a little more than one-third of the length of the head ; 

 the last spine is a little longer than the penultimate ; the soft dorsal 

 is somewhat elevated and not scaly. The three posterior anal spines 

 are nearly of equal length and strength, two-fifths of the length of 

 the head. Caudal rounded, scaly at the base, one-fourth of the total 

 length. 



Scales minutely ciliated. 



The jaws, vomer, palatines, and upper and lower pharyngeals are 

 armed with bands of small, villiform teeth, the jaws having a pair 

 of small canine-like teeth anteriorly. The roof and the bottom of 

 the cavity of the mouth have an elongate band of granular teeth, 

 the lower not being confluent into one plate. 



The coloration appears to have been uniform. 



Two specimens, 54 lines long, were transferred from the collection 

 of the East India Company to the British Museum. 



PsEroOCHROMIS PERSPICILLATUS. (PI. XXVII. fig. C.) 



D. §r. A. fr. L. lat. 45. 



Reddish-olive (in spirits), with a chestnut-brown band running 

 from the extremity of the upper jaw through the middle of the eye 

 to the middle of the base of the dorsal fin ; the band is very dark 

 and slender anteriorly, gradually becoming lighter and broader poste- 

 riorly. 



China. 



Description. — The height of the body equals the length of the 

 head, and is contained thrice and a third in the total (without caudal) . 

 Head longer than high ; cleft of the mouth oblique, with the jaws 

 subequal anteriorly, and with the maxillary extending to behind the 

 vertical from the front margin of the orbit. Snout a little longer 

 than the orbit, the diameter of which is one-fourth of the length of 

 the head. The width of the interorbital space, which is scaly, is less 

 than that of the orbit. The lower jaw with two, the upper with 

 three pairs of canine teeth. Scales on the cheek in six series. 

 Caudal fin subtruncated, with an upper and lower ray produced into 

 a filament. 



Several specimens are in the collection of the British Museum ; 

 one of the largest is 42 lines long. 



Amblyopus sagitta. (PI. XXVII. fig. A.) 



The height of the body is one-twelfth of the total length ; vertical 

 fins united ; caudal very long, arrow-shaped ; teeth small, in a single 

 series ; eyes rudimentary. 



California. 



Description. — Body elongate, compressed, covered with small, im- 

 bricate, cycloid scales, which become larger posteriorly. Head elon- 

 gate, subquadrangular, one-seventh of the total length (veith the 

 caudal), and two-thirds of the distance between vent and base of the
