8. Amphistoma * Small intestine of black scoter (Oidemia nigra). 



9. . . Small intestine of crow {Corvus Corone). 



[ . . Intestines of turtle {Chelonia imbricata).'] 



* I only once met with this species of Amphistoma, and have only 

 a single specimen ; it was alive when removed from the intestine of 

 the bird. It is nearly two lines in length ; the head distinct, about 

 half the length of the body, whiter, and more cylindrical ; body flat- 

 tened and wider, the edges crenate. The pores appear to be of equal 

 size ; if there is any difference, the anterior is rather larger ; it is also 

 rather inferior than terminal. The oviducts run along each side of 

 the body near the margin, and appear to contain numerous ova ; a 

 yellowish canal is seen in the median line, commencing where the 

 head and body join, and passing backwards towards the terminal 

 pore.

 I have found this species in great abundance and perfection in 



Lord Fitzwilliam^s park at Milton. The flesh when broken be- 

 comes red, the substratum of the pileus is beautifully silky, and 

 there is a pecuharity about the habit ; besides it is not edible ; 

 still it must be confessed that it is extremely near to Ag. procerus, 

 to which it has been referred by authors. There is no doubt, 

 notwithstanding the hesitation of Fries, that Sowerby^s figure, 

 tab. 190, represents the true Ag. procerus. I take this opportu- 

 nity of remarking that Ag.piJuliformis, Fr. Ep. p. 25, is nothing 

 more than the young of Ag. spadiceus, as indeed is noticed in the 

 text of Bulliard and Ventenat. 



258. Ag. ch-ysodon, Batsch, f. 212. 



This very beautiful species occurred in profusion in a wood at 

 King's Cliffe in the autumn of 1842. I had never seen it pre- 

 viously. It not only grew under the lime-underwood, but amongst 

 grass in the open glades. It resembles very closely in many re- 

 spects Ag. eburneus, but is beautifully distinguished by the golden 

 yellow pubescence which is sprinkled here and there over the 

 plant, but principally on the stem and margin of the pileus. 

 Sometimes the gills are elegantly edged with yellow flocci. The 

 smell is strong, like that of Ag. cossus.
