Dr. Richardson's Contributions to 



tical row, two of which arc above the lateral line. The lateral line 

 runs straight until it arrives under the posterior part of the dorsal, 

 when it makes a descending curve and becomes straight again ; it is 

 composed of scales smaller than the others, as in Sc. Vosmeri. 



Rays :— Br. 5 ; D. 10|9, the last one divided ; A. 3j7 ; P. 17 ; C. 

 154; V. 1|5. 



The dorsal spines arc slender and acute ; the fourth is the tallest, 

 and the tenth is a little shorter than the second, but one-third longer 

 than the first, which again is nearly half the length of the fourth. 

 The third is the longest of the anal spines, and the first is nearly half 

 as long as the second one. The ventrals are drawn out into a short 

 filamentous tip. The caudal is lunate on the margin, the upper lobe 

 being a little longer than the lower one. 



The colours of the dried specimen have faded, but a pale band can 

 still be traced from the upper part of the gill- opening to the caudal 

 fin, coinciding with the lateral line after its curve. There were 

 perhaps two other stripes higher on the back, but the vestiges of 

 them are very obscure. The belly below the level of the pectoral 

 is pale. The scales of the back and sides are each marked by a 

 dark stripe parallel to its exterior margin.

No. 20. Lieut. Emery's drawings. 



Lieut. Emery's portfolio contains a drawing of an Amphi- 

 prion taken at Depuch Island, which resembles the polymnus 

 of Bloch. It is less elevated at the pectoral fins, and its soft 

 dorsal and anal are rounded and not angular, but its form in 

 other respects is much like that of Anthias Clarckii (Ben. 

 Fishes of Ceylon, No. 29). Its resemblance to a Chinese Am- 

 phiprion, which is perhaps the chrysopterus of the ' Histoire 

 des Poissons/ is still more striking, the chief difference in form
