ture males only, but Sars had both sexes of E. goesii at bis command 
when drawing up bis description. Of tbe present examples 5 are 
females and 3 males, but ali bave serrulated inner uropods. 
E. goesii must, tberefore, be deleted from tbe Mediterranean list. 
E. elegans bas been recorded from the Mediterranean, from Messina 
and Naples by Sars. 
15. I^arerythrops lobiancoi sp. n. 
P. obesa^ Lo Bianco (1903; nec G. 0. Sars, 1870). 
PI. 7 Fig. 1—6. 
General form (Fig. 1) small, compact and rather robust. 
Carapace wider than the pleon, covering almost entirely the 
thoracic segments; anterior margin obtusely rounded; cervical sulcus 
well marked. 
Pleon longer than tbe carapace; 1. segment slightly shorter 
than the subequal 2. to 5. segments; 6. segment slightly greater 
than twice the length of the 5. segment. 
Eyes well developed and normal in structure; greatest width of 
the cornea approximately equal to the width of the last pleon 
segment; pigment in preserved specimens light golden brown. 
Antennular peduncle (Fig. 2) slightly shorter than the 6. seg- 
ment of the pleon, robust; 2. Joint very short, 3. Joint longer than 
the first; inner flagellum much more slender than the outer. 
Antennal scale (Fig. 3) extending slightly beyond the distai end 
€f the antennular peduncle; more tban 3 times as long as the 
breadth at the spine on the outer margin and narrowing considerably 
towards the base ; outer margin considerably arcuate and terminating 
in a strong spine beyond which the apex of the scale is produced 
for one quarter of the entire length of the scale; no spine on the 
outer distai corner of the basai Joint. 
Antennal peduncle (Fig. 3) slightly shorter than the antennular 
and less robust; 3. Joint longer than either the first or second. 
Mouth parts and 1. thoracic limb (Fig. 4) agreeing in ali essen- 
tial particulars with the same appendages of P. obesa. 
2. thoracic limb (Fig. 5) somewhat longer proportionately and 
more slender than the same limb in P. obesa; carpus longer than 
themerus; propodus small and densely armed; no distinct dactylus. 
3. — 8. thoracic limbs broken off in ali the specimens. 
Pleopods of both sexes agreeing substantially with those of 
P. obesa.
