THE KILIMA-NJAE0 EXPEDITION. 
APPENDICES. 1 
1. Note on a Nematoid Worm (Gordius verrucosus ) obtained by 
Mr. H. H. Johnston on Kilima-njaro. By F. Jeffrey 
Bell, M.A., F.Z.S. 
The single specimen of Gorclius which was obtained by Mr. John¬ 
ston belongs to a well-known and widely-distributed species, but yet 
presents points of interest such as are almost always absent from so- 
called new species. 
So far as my knowledge extends (and on this particular point it is 
in advance of that of Dr, Linstow, who, in his valuable “ Compendium 
der Helminthologie,” does not mention the parasite now under con¬ 
sideration), Gordius verrucosus is in earlier life parasitic on a species 
of the genus Mantis ; and there is in the British Museum a specimen 
of “ Mantis , sp.,” which, as Mr. Waterhouse has been good enough to 
point out to me, is really M. membranacea, accompanying a Gordius. 
The whole of the abdomen of this Orthopteron is completely emptied 
of its contents. A similarly excavated Mantis , the appearance of 
which had excited Mr. Waterhouse’s wonder, is to be found among 
the insects collected by Mr. Johnston between 3000 and 5000 feet. 
A specimen, belonging apparently to the same species, is to be 
found half-in and half-out of the abdomen of Hierodula bioculata , a 
Mantid collected on the west coast of Africa, and lately presented to 
the trustees by Dr. Gunther, F.R.S. 
With regard to the geographical distribution of the species, it is to 
be noted that it is sufficiently wide to include South Africa and 
Ceylon; while there are in the British Museum specimens named 
respectively by Dr. Baird, the author of the species, and by Dr. Orley, 
who in 1881 went carefully through the collection in the Museum ; 
these specimens are reported as coming from Yera Paz, Guatemala 
(presented by O. Salvin, Esq.), and the “ neighbourhood of Irazu, Costa 
Rica” (presented by Messrs. Godman and Salvin). The fact that the 
same parasite is to be found in hosts of different species is well
