depression which corresponds to ridge (Figure 
18B). Head slender; HLI males 20.6-25.6-29.6 (SD, 
2.8), females 16.1- 23.2 -31.9 (SD, 4.5); narrower 
than mantle; HWI males 29.0 -35.3 -41.7 (SD, 3.8), 
females 28.9- 35.6 -40.9 (SD, 4.2). Eyes moderate 
size, EDI males 11.2 -12.5 -14.9 (SD, 1.2), females 
8.6- 11.2 -14.1 (SD, 1.5); ventral eyelids present. 
Male and female arms subequal in length (Table 
9). ALI of longest arms in male 30.4- 36.4 —42.5 (SD, 
4.0), females 32.7- 35.3- 39.1 (SD, 2.2). Protective 
membranes (both sexes) wide, well developed; 
normal, not thickened. Distal arm tips (both sexes) 
strongly attenuate, suckers enclosed by protective 
membranes. Arrangement of arm sucker rows 
differs between sexes. In males, sucker rows on 
arms 1-3 biserial proximally (approximately 8-11 
rows biserial suckers arms 1, 6-8 rows biserial 
suckers arms 2 and 3), tetraserial distally; arms 4 
suckers biserial at base (approximately 2 rows), 
suckers tetraserial distally. In females, sucker rows 
on arms 1-3 biserial proximally for 6-7 rows, 
tetraserial distally; suckers on arms 4 biserial 
proximally for 2-3 rows, rest tetraserial. Suckers in 
males normal in size (not greatly enlarged); larger 
than female arm suckers (Table 9). Chitinous rims 
of arm suckers smooth, or with blunt processes on 
inner ring; infundibulum with 9-13 rows of ovoid- 
hexagonal processes with blunt pegs, inner row
