16 PROF, E, A. MINCHIN ON THE [May 2, 
the original of Bowerbank’s fig. 7 on pl. ii. of Brit. Spong. vol. i11., 
is at the top over the middle of the card; the other six arein two 
vertical rows of three each to right and left. As I have stated 
elsewhere, J have examined six out of these seven specimens, and 
all of them, except the larger one at the top, are quite typical 
specimens of Lewcosolenia complicata ; the large specimen alone is 
atrue Clathrina. 1 give figures of its spicules (text-fig. 4, 4 a—4/), 
and it is not necessary for me to describe them in detail, for it is 
evident from the figures that this specimen agrees with the true 
contorta in all respects but one, namely, in that the monaxons are 
wanting. In short, Bowerbank’s type-specimen of ‘“ Leucosolenia 
contorta,” or, to be more accurate, the only one of his type- 
specimens which does not belong to a species of prior standing, 
is a specimen of “‘ Ascetta spinosa” Lendenfeld ! 
I have also examined two other specimens of Bowerbank’s*, 
given by him to Canon A. M. Norman, and now in the latter 
gentleman’s collection. The first of these was sent by Canon 
Norman to Haeckel, and returned by him after examination. It 
has the following label in Norman’s handwriting :— 
“ Teucosolenia contorta Bow. 
““ Guernsey 
“(A type-specimen from Dr. Bowerbank).” 
Also a label in Haeckel’s handwriting :— 
“ Ascandra contorta H. 
ue (Leucosolenia contorta Bwhk.) 
“ Guernsey, Bowerbank.” 
If any specimen in the world ought to have been a specimen of 
contorta, surely this ought, bearing, as it does, a double testimonial 
to character from the two founders of the species. What, then, 
was my astonishment, on examining the spicules, to find it a quite 
typical example of Leucosolenia variabilis Haeckel! I figure its 
spicules in text-fig. 5, 7a—-71. The only point to notice about them 
is a certain admixture of Sycon spicules (7%, 71), which, as I have 
set forth in another place, frequently occurs in preparations of 
variabilis. 
The second specimen in Canon Norman’s collection bears a 
label in Bowerbank’s handwriting as follows :— 
“ Leucosolenia contorta, Guernsey.” 
According to information furnished me by Canon Norman, this 
particular specimen was not sent to Haeckel, but it is one of the 
same lot as the type sent to him, and has an equal claim to be 
regardedas atype. Examination of the specimen shows a mixture 
of Leucosolenia complicata and Clathrina coriacea (text-fig. 5, 
8 a-8 m). 
* Bowerbank in his Monograph mentions twenty-eight specimens of contorta, but 
I have had access to only nine of them, Ido not know what has become of the 
others.
