the bands present or absent ; sometimes a well-marked cross-band 

 on the rump ; sides dark brown with yellow spots ; upper surface 

 of limbs lighter brown with yellow spots, sometimes of moderate 

 size and scattered, but more commonly in small freckles ; lower 

 parts creamy white. The yellow markings are frequently replaced 

 by white; (b) general color much ligliter brown, the yellow or white 

 spots or bands being replaced by pale brown or dirty white ; other- 

 wise as in var. a. In some young examples tlie upper parts are 

 so profusely blotched with white as to almost entirely hide the 

 dark ground color, but as a rule the pattern of coloration as given 

 in the description of var, a is not materially departed from. 



This Tree Frog appears to be common in the St. Joseph's River 

 district, since no less than twenty six specimens were sent down 

 by Sir AVm. Macgregor, to whom I have much pleasure in dedi- 

 cating this handsome species. The largest example measures 30 

 mm. from snout to vent. 



PISCES. 



T regret to say that of the ten specimens forwarded all are 

 eitlier too young, or in too bad a condition to admit of accurate 

 specific identification; they belong however to the following 

 genera : 



Eleotris, ap. 



Two examples of what may possilily be the young of Effotris 

 porocfiplia/ns, C.Y. 



Elkotris, sp. 

 A single very young specimen. 



Salarias, sp. 

 A single very young specimen. 



Plotosus, sp. 



Five specimens, the largest of which is little more than one inch 

 in length ; they are in all probability the young of P. ccmius, 

 Ham. Buch. 



Syxgxatiius, sp. 



One example, which is perhaps the young of S. spicifer, Riipp.* 



* Owiny: to my non-reception of a second proof of iny paper on a new 

 Tetrodou (see paaje 81) the error in the foot-note has been overlooked : 

 my meaning would he better shown thus — read after " dorsul fin," vliich 

 is equal to the distance betiveen that point and the termination of the dorsal 

 fin." The lapsus calamiin ilie first line of the description, viz. the substi- 

 tution of " of " for " Ml " must be apparent to all.
