1 One of two specimens (£ $ ) in tube labelled 
‘ figured specimens,” 
here selected 
is Holotype. 
2 Syntype of var. austrinorum. 
3 Specimen approaching typical form. 
* Specimen approaching var. austrinorum. See 
remarks below. 
Remarks. — The great majority of the 
specimens obtaine 
1 by 
the 
“Terra b 
OYcl 
agree closely with the “Discovery” specimens that form the types of the variety 
austrinorum. There are. however, a number that, in their smaller size, longer legs, 
and more strongly built and hairier bodies, approach the typical form of the species 
without its being possible to separate them definitely from the others. I am not 
prepared to express an opinion as to the status of the variety austrinorum, but it may 
not be without significance that, of all the “Terra Nova” specimens, those that 
approach most nearly to the typical cmstrale- form are the four obtained at Station 220, 
off Cape Adare, the type-locality for the species. 
Bouvier’s Nymph on stylops appears to differ in no essential feature, as far as his 
description and figures go, from the typical form of this species.
