This species is common on the New Zealand coasts, and I have series 
T specimens from several localities. There are great differences in the 
length of the RENTY especially of the peus antenna, and in the shape 
of the gnathopods, due to age and sex. In the more mature males the 
second antenna Б = considerably in length, especially in that 
of the peduncle, and the second gnat thopod becomes sot large and 
o be identical with the one described by Chevreux under the name of 
Stenothoe dollfusi, and it is apparently this form that Kunkel had before 
im when recording Stenothoe valida from the Bermudas. As I have found 
the two forms Stenothoe valida and S. dollfusi together on two separate 
occasions in Cook Strait, and as both forms also occur together in Port 
Jackson, New South Wales, and apparently elsewhere, I have little doubt 
that they both belong to one species, and that we have here another 
example of a species with dimorphie males. 
In the older males the mouth-parts appear to become degenerate. 
I have, however, discussed this question more fully, and also the reasons 
for referring the species to the one ME rer described by Dana, in 
the Records of the Australian Museum, vol. 14, p. 
I have recently received specimens from the Hawaiian Islands which 
appear to belong to this species.

In 1909 I referred to this species specimens from the Auckland Islands ; 
but it has not hitherto been recorded from the coasts of the main islands of 
New Zealand. І have now, however, in my collection numerous specimens 
from different localities extending from the Three Kings to Otago Harbour. 
These are all much smaller than the specimens from the Auckland 
tends none of them measuring more than about 8 mm. in length, but they
