markings being much more like, but the colour wholly dis- 
similar. Primaries sandy buff, crossed by about seven lines or 
stripes of sap-green, but all ill-defined, excepting towards the 
inner: margin, where they become blackish ; all these lines 
excepting the fourth are regularly zigzag or undulated, the 
fourth is regular and oblique, excepting at its extremities, 
which are angulated; the second and third and the fourth and 
fifth lines are most prominent, and, being near together, pro- 
duce the effect of two narrow divergent bands: secondaries 
sandy buff; an arched dusky line near to the outer margin, 
and on each side of it upon the abdominal border a rather large 
dusky spot, the outer or inferior one being placed at the anal 
angle and surmounted by a small whitish border; external 
area beyond the dusky line somewhat greyish: body sandy 
buff, tegulee bordered externally with sap-green. Under sur- 
face creamy ochreous : primaries with the discoidal cell greyish 
in the centre; discocellulars and a tapering submarginal streak 
also greyish; external border whitish; fringe dark brown: 
secondaries with faint indications of two slightly divergent 
and darker lines, dusky towards the abdominal margin, the 
outer one widely arched; anal angle greyish; abdominal area 
whitish; legs above slightly brownish. Expanse of wings

It is possible that the upper surface of the primaries may 
be wholly greenish in freshly-caught examples, since green 
almost always sooner or later fades to buff-yellow.

X LIX.—Remarks on the Genus Solaster. 
By D. C. DANIELSSEN and J. KorEn*. 
THE genus Solaster, first established by Forbes, has at 
different times been subjected to various criticisms, cer- 
tain authors, such as Liitken, Duncan and Sladen, and A. 
Agassiz, having expressed the opinion that its two species, 
Solaster endeca and S. papposus, ought to be placed in two 
genera. Agassiz has adopted for that containng S. pap- 
posus, Miiller and Troschel’s denomination Crossaster; while
