rectangular crank-shaped stripe just beyond the middle ; a 

 pearly-centred reddish spot within (as well as at the end of) 

 the cell : secondaries with a zigzag reddish stripe beyond the 

 middle : palpi red-brown above, white below ; head and 

 thorax yellow, centre of prothorax reddish; abdomen brownish 

 (perhaps discoloured). Under surface altogether paler, with- 

 out markings. Expanse of wings 1 inch 5 lines.

XXXIV. — On the SyringosjyJiceridce., an Order of Extinct 

 RMzopoda. By Prof. P. Martin Duncan, M.B. (Lond.), 

 F.R.S., &c. 



The late Dr. Ferd. Stoliczka collected some very remark- 

 able spheroidal fossils in the Karakorum range of mountains, 

 in strata beneath the Lias, and of an age which may be Rhaetic 

 or Triassic. His lamented death prevented his describing 

 these so-called " Karakorum stones ;" and Mr. W. T. Blan- 

 ford, F.R.S., forwarded me the specimens, with a request from 

 Mr. Medlicott, F.R.S., Director of the Geological Survey of 

 India, that I should describe them for the forthcoming volume 

 on the " Mission to Yarkand." Having carefully investi- 

 gated the nature of these remarkable forms, I can come to no 

 other conclusion, than that they will not fall within any known 

 order in our classification^ and that two genera must be founded 

 to receive them. 



As the description of the forms, illustrated by drawings, is 

 to be published, it is only necessary to give an abstract at 

 the present time. But, first of all, it must be noticed that 

 these large spherical and spheroidal stones are not quite new 

 to science. In 1867 Dr. Vauch^re, in a paper on the geo- 

 logy of Kashmir, mentions them, and describes some as 

 8phceron{tes, giving very bad drawings of the outside only. 



In the museum of the Geological Society there is a speci- 

 men derived from Kashmir, and presented by Captain (now 

 Col.) Godwin- Austen in 1864. It bears the title Sjyhmro-
