swellings further back, but still in the antero-dorsal region. M. 

 Novak supplies also a table of the vertical distribution of the Phyllo- 

 carida in Bohemia. 



In the Annales XIII. Soc. Geol. du Nord, 3 me Livr. April, 1886, 

 p. 146, M. E. Canu gives a resume of the results of M. 0. Novak's 

 researches in the Phyllocarida, with some woodcuts of Aristozoe 

 regina, Bactropus longipes, and Ceratiocaris debilis (see Third 

 Eeport, pp. 32-34), and of Ptychocaris simplex (see above). 



26. Dr. A. S. Packard, jun., has described, and figured some 

 peculiar appearances on an internal cast of a Carboniferous Phyllo- 

 podous carapace from Illinois, as traces of four pairs of lamellate 

 limbs (thoracic feet), probably " the homologues of the exopodites of 

 Nebalia." He has defined the genus and species as Cryptozoe pro- 

 blematical (American Naturalist, Extra, Feb. 1886, p. 156 ; and 

 Proceed. Americ. Philosoph. Soc. vol. xxiii. No. 123, pp. 380-383). 



27. In a Geological Eeport, Assembly Document, No. 161, 1885 

 (or 1886), Mr. J. M. Clarke has defined the localities and geological 

 succession in Ontario County and New York, where the Phyllopods 

 which he previously described (see ' Second Report,' 1884, pp. 80-86, 

 and ' Third Eeport,' p. 3) have occurred with or without Goniatites. 



28. A list of the British Palaeozoic Phyllocarida described in the 

 Third and Fourth Eeports is given on the preceding page (p. 461).

^WO short papers in this part relate to the disputed age of the 

 beds in the Salt Eange, containing species of Conularia. The 

 first is " A Note on the Olive Group of the Salt-range," by E. D. 

 Oldham, A.E.S.M., and the other " Memorandum on the Discussion 

 regarding the Boulder-beds of the Salt-range," by H. B. Medlicott, 

 F.E.S. Mr. Oldham visited the locality in the Salt-range, in which 

 the Conidaria beds occur, and states that the thin band of gravel in 

 which they appear is the last kind of rock in which one would 

 a priori expect concretionary nodules to be formed. At the same 

 time he believes that for the most part these fossiliferous pebbles 

 were originally concretionary nodules, and that they have been 

 transported into their present position. From the character of the 

 associated pebbles in the beds beneath, he believes that the original 

 position of the beds from which the Conularias come must have been 

 to the southward of where they now are. He further concludes 

 from the stratigraphical relations of the beds, that the Olive group 

 (including the gravel-bed with Conularia) is homogeneous, and must 

 be associated with the overlying nummulitic beds, rather than with 

 the underlying Palaeozoic or early Secondary beds. 



Mr. Medlicott does not admit that the petrological evidence brought 

 forward by Mr. Oldham is altogether conclusive as to the transported 

 origin of the fossiliferous pebbles, though it would be -''almost absolute 

 if he could assert that the ground-mass of the gravel-bed is quite
