side from pectoral to caudal, tending rarely to form a continuous band, 

 above which the back is irregularly freckled with dusky specks of different 

 sizes : the two dorsal and the caudal fins are also minutely speckled with 

 dusky ; the other fins and the lower-parts pale and spotless. The largest 

 of several specimens measures If in. 



G. coEYPHiENULA, Valenciennes. This curiously formed species ap- 

 pears to be very common both at the Andamans and Nicobars, frequent- 

 ing the coral-reefs. 



Apogon quinquevittatus, nobis, n. s. About 1 in. in length, with 

 four vertical black bands, a fifth at base of tail, and the occipital region 

 also of this colour. Form compressed ; the month small ; scales also 

 small, numbering about 24 to end of lateral line, which terminates at the 

 posterior base of the second dorsal fin, and 3 rows above and 10 below 

 the lateral line, downward from the first dorsal. Eye large, occupying 

 two-fifths of the vertical height of the head.

Pectorals reaching beyond the second lateral band ; the posterior dor- 

 sal and the anal fins projecting similarly as far as the base of the tail-fin. 



Miceopkis tenuis, nobis, n. s. A very slender Syngnathous fish, with 

 16 body and 36 caudal rings, and dorsal fin upon the first 7 caudal rings* 

 D. 24?— P. 16?— C. 9? 



Snout half the length of the head, and scarcely more compressed than 

 the neck ; body slightly heptangular, the two dorsal angles alone strong- 

 ly marked ; tail quadrangular, and nearly twice as long as the head and 

 body. Dorsal aspect unmottled brown ; the other facets of the body 

 (between the angles) marked, more or less distinctly, each with a white 

 band, the continuity of which is broken at the rings : on the tail similar 

 markings are but slightly indicated : no silvery appearance at the gill- 

 covers. Described from two female specimens, the longer of TC^iich mea- 

 sures nearly 4 in. 



Of Mollusca, 22 marine species were procured; but all of them are 

 well known kinds, common in the Bay, and which need not therefore be 

 enumerated. 



Among the Crustacea are five specimens of a magnificent land-Crab, 

 which sufficiently agrees with the description of Caedisoma caenieex. 

 (Herbst), by Milne Edwards; but which are nevertheless probably dis- 

 tinct and new, as no land-Crabs approaching them in size seem to be 

 known on the peninsula of India. There are two marked varieties (one 

 of them probably the result of former mutilation of a claw), each attain- 

 ing to above 3 in. across the carapace. In one of these varieties the claws 

 of the male are excessively unequal, and the huge nippers of the great
