like the oyc-spots of //. argus, but here the outer browa rim is 

 a -woll-definod line, instead of shading ofF gradnally eentripetally ; 

 moreover, there is no central dark spot. In the largar patches, 

 there may be a papilla in the centre of each component circle, but 

 in the very largest, it is not possible to observe the papilla). Tlu; 

 patches along the edges of the dorsum are more or less circular, 

 measuring 1 — 2 cm. in diameter, and on the whole form a row 

 on each side. In general, the dorsum looks like the map of an 

 archipelago consisting of numerous large and small islands of all 

 sliapos, and well supports the name marmorata. 



On the ventrum the ground color is white. There is an ill- 

 definod longitudinal band of a dark sooty color occupying about 

 one-third of the vontrum. in this streak, surrounded by white 

 spaces, are yellow- oclu'e patches of the same type as on tlie dor- 

 sum but generally of only small sizes. Of these there arc 

 roughly speaking two longitudinal rows, one on each side of the 

 mtKlian line. Outside of the sooty Ijand, there is on each side 

 an irregular row of the same patches, closely bordering on tlie 

 darker dorsum. These lateral rows consist on the whole of larger 

 patches than those near the median line, most of them being 

 about 1 cm. across. Tlie patches on the xentruin show no central 

 papiUa. 



In alcohol, tlic colors are arranged as in the living specimen, 

 but the ground color of the; (k)rsum has acquired a purphsh tinge. 

 The ochre-yellow patches now appear dark-brown or mars-brown, 

 and those on the sides are more conspicuously visibk' than those 

 on the more dorsal parts, as the white of the ventrum seems to 

 extend around those patches and make them stand out distinctly. 

 In the inact'rated specimen (No. 1047) the colors are much faded, 

 and tl;o irregular patches appear light on the general auburn
