ensigera intermediate (mean 1.17). On this basis H.e. australiensis 
and H.e. ensigera are doubtfully distinguishable. 
Length carapace/length rostrum ratio: In H.e. australiensis the 
ratio is high (mean 4.77), in H.e. californiensis low (mean 4.05), and 
in H.e. ensigera intermediate (mean 4.54). 
Length/breadth ratio of cornea: In H.e. australiensis the ratio 
is low (mean 1.20), in He. californiensis high (mean 1.32), and in 
H.e. ensigera intermediate (mean 1.27). 
Length of eye/breadth of cornea: In H.e. australensis the ratio 
is low (mean 1.32), in He. californiensis intermediate (mean 1.46), 
and in H.e ensigera high (mean 1.51). On this basis He. californi- 
ensis and H.e. ensigera are indistinguishable. 
Type specimens of the three subspecies are designated as follows: 
H.e. australiensis, male, carapace length, 28.5 mm, 12 miles E. 
Broken Bay, NSW, Australia, presented by H. Arnold, November 
1946, AM reg. no. P.11695. 
H.e. californiensis male, carapace length, 41.1 mm, Southern 
California, Anton Dohn coll., gift Venice Mar. Biol. Sta. 1909, USNM 
50016. 
H.e. ensigera Manning (pers. comm.) has informed me that the 
type of H. ensigera is a dry specimen in the collection of the British 
Museum (Natural History). I have not had an opportunity to study 
the specimen.
