HORN EXPEDITION—CRUSTACEA. 
Lines of growth, 30-50, crowded towards the margin. Setse rarely present 
except round the outer margin. The sculpturing of the umhonal portions of the 
shell resembles that of var. typica. Towards the margin, owing to the crowding 
of the lines of growth and the strong development of the radial lines, which are 
unhranched in this region, the ornament becomes cancellated. The lines of growth 
have minute rounded prominences at the junction of the radiating lines with 
them, and thus have a moniliform appearance. The strongly-marked cancellation 
is a very characteristic feature of the variety. 
The dorsal spines on the telson are fewer in number than in var. typica, and 
very irregular in shape and size. 
Colour reddish-brown, darker than var. typica. 
E. packardi, var. minor. 
Carapace tumid. 
Measurements of average specimen:—Length, 4 mm. ; height, 2‘7 mm. ; 
thickness, 2 mm. 
Lines of growth about thirty. Numerous long white setie on all the lines of 
growth. Sculpture much as in var. cancellata, but the deep cancellated ornament 
not so marked, and the moniliform ornament absent. 
Telson and colour of carapace as in var. typica. 
Eulimnadia.
