last articulation, however, is not so stronglj'- marked as the 

 rest. The head is large, ovate, with two red eyes in front, 

 and two short, conical, obscurely-articulated antennae; the 

 mouth is furnished with two strong maxillae, which, when the 

 animal is at rest, are completely retracted and out of sight. 

 The first articulation of the body is furnished with two short 

 feet, crowned at their extremities with a few short bristles. 

 Down the centre of this and the following articulations is a 

 dark line, marking the situation of the intestines. The last 

 joint is also furnished with two short conical feet, or append- 

 ages crowned with short bristles, and a conical projection in 

 the centre, crowned with about eleven pellucid cilia, which 

 are undoubtedly the temporary lungs. I have frequently seen 

 the animal comb them out with his large maxillae. On each 

 side of the branchial tubercle is a short conical appendage. 



I must leave entomologists to decide the affinities of the 

 little larva, and must beg them to pardon any errors in my 

 description of it. I did not witness any further change, as 

 the larvae soon died, and the mass became clothed with mu- 

 cedinous filaments.

XLV. — Supplement to descriptions of Exotic Fungi in ^ Annals 

 of Nat, Hist,,' vol. iii. pp. 322 and 375. By the Rev. M. J. 

 Berkeley, M.A., F.L.S. 



Since the publication of the tw^o memoirs cited above on the 

 Exotic Fungi in the collection of Sir W. J. Hooker, the dis- 

 covery of a packet of Dr. Richardson's Arctic Fungi which had 

 been mislaid, and the publication of Fries's ^ Epicrisis,' w^ho 

 had received many of the species from Klotzsch, makes it 

 necessary to give a short supplement. I have also to thank 

 Dr. Montague for one or two suggestions, of which I have 

 availed myself in the following notes : — - 



1. Lentinus villosus, 1. c. p. 322 = L.fasciatus, Berk., Hook. 

 Journ. of Bot. v. ii. p. 146. t. 5. 



2. Polyporus vesparius, 1. c. p. 323. The specific name, as 

 Dr. Montague very properly remarks, is too near that of Pol,
