ate. The lower part of the mandible is covered by small hairs, 
placed in groups of two or three. — The maxi 11a has somewhat 
arched cutting edge with long spines, of which only the upper one is 
a little more prominent. Only a narrow zone along the edge is hairy. 
The rami of the c i r r u s I are much 
alike with globose segments, and only 
differ in their numbers of segments, 
the anterior having 10 or 11, the post- 
erior 11 or 12 segments. There is a 
distinet interval between cirrus I and II; 
also in cirrus II the anterior ramus 
has somewhat swollen segments. The 
number of segments in the rami of 
cirrus II to VI counts from 18 to 22. 
The caudal appendages consist 
of a feeble apophysis and a small glob¬ 
ose, distal segment; two larger and 
four or five smaller hairs are placed 
distally on the appendage. 
The penis is about half as long 
as the cirrus VI; it is sparsely hairy 
all over, and has no special tuft at its Fig 8 - Scal P elIum caiifornicum, off

Scalpellum aff. salartiæ Gruvel. 
15 miles W. V* S. of Jolo; 250 fathoms. 27/III 14. One specimen. 
Gru vel (1905, 1901) in his description of Scalpellum salartiæ 
says „Rostre quadrangulaire, légérement recouvert par les extré- 
mités umbonales des rostro-latérales“ ; this taken together with his 
drawings tells us that the rostrum in this species is rudimentary, 
and therefore probably variable in size and shape. Moreover, the 
small size of Gruvel’s specimen — total length 2,5 mm — seems 
to indicate that the species has been based on a very young spec¬ 
imen. No weight can therefore be ascribed to the rostrum of the 
present, larger specimen being very small, and triangular, and not 
direetly covered by the edges of the rostral latera. Also the some¬ 
what irregular, and scantier armature with scales of the peduncle 
in Gruvel’s specimen may be due to its smaller size, as is evident
