 hall' as IdUL; as the tibia', constructed exactly as in 'IVichaldiiluis, the iiid\- 

 living geuus of Al()i)liina' 1 have been able to examine 'Hie tore coxaj are 

 attingent, the middle coxai narrowly, the hind coxa- \vid(d\ separated, the 

 last by nearly the diameter of the coxal cavities. The third and fourth 

 abdominal segments are shorter than the others but not xcvy short, being 

 together a third longer than the second; the first and second segments are 

 separated by a straight suture. 



It is noticeable that in the fi>i-nls with shoi-t rostrum, the specimens are 

 preserved about as often on a doi-sal as on a latiTal \ie\v, while in tliose 

 with long i-ostrum, it is rare to iind one presei'ved other than 1\ ing uiiou its 

 side; it is not unlikeh' tliat in the former the bod\- ma\ be relativel\- 

 more depressed, in the later more compressed than in the alternate type. 



Nine species ai'e known, all from Florissant, and from Fh)rissant (m]x, 

 where it is the most al)undant type of Khynchophora, and may be regarded 

 as typical of these beds.
