the last including such forms as Lepralia violacea, which in all essential characters is an 
Adeonean ; and perhaps Lepralia innominata, and several fossil forms. 
The number of species belonging to the Family in the Challenger Collection does not 
exceed seven or eight and includes only one typical Adeona. But the number of forms 
referrible to it leaving aside those whose identification is impossible from the imperfect 
descriptions published, and most of which have come under my own inspection, is very 
considerable, as will appear from the subjoined probably very incomplete list. 
In his Monograph of the Genus Adeona Dr. Kirchenpauer 1 enumerates about eight 
forms which he regards as species, viz : — 
(1) Adeona foliacea or foliifera, Lamx. and Lamk. 
(2) Adeona intermedia, Kirchenpauer. 
(3) Adeona macrothyris, Kirchenpauer. 
(4) Adeona arborescens, Kirchenpauer. 
(5) Adeona grisea, Lamouroux. 
(6) Adeona cellulosa, Macgillivray. 
(7) Adeona albida, Kirchenpauer. 
To which have been since added : — 
(8) Adeona wilsoni, Macgillivray. 
Besides these published species I am acquainted from direct observation with five or 
six others that I have not been able to identify with any of the foregoing, and which will 
be included in a projected memoir on the genus which I hope to be able shortly to 
prepare. 
(9) Adeona appendicidata, n. sp. , Australia. 
(10) Adeona gattyce, n. sp., South Africa. 
(11) Adeona lancifera, n. sp., Australia ? 
(12) Adeona valga, n. sp., Australia. 
(13) Adeona microthyris, n. sp., Australia. 
(14) Adeona lycopodioides, n. sp., South Atlantic. 
Of these a single specimen of the first only occurs in the Challenger Collection, and 
is here described. For the second I have long been indebted to the kindness of Miss 
Gatty, to whom I also owe several species of Adeonella. 
Adeona valga and Adeona lycopodioides have been for many years in my collection, 
whilst Adeona microthyris appears to me to be a new species contained in a magnificent 
collection of Australian Adeonese, lately sent by Mr J. Bracebridge Wilson to the British 
Museum.
