146 ; NOTARCHUS. 
The body-color is gray yellowish; at the bases of the processes 
there are spots, part simple, part ocellated, the former dark brown ; 
the small ocelli are formed of a white center surrounded by small 
closely placed or confluent dark brown flecks. 
Near Tor, Red Sea, found in April in small families, or thrown on 
the beach. (Ruppell). 
Notarchus laciniatus Rupp. & Leuck., Atlas zu der Reise im 
Nordlichen Afrika von Eduard Rtippell, Neue Wirbellose Thiere 
des rothen Meers, p. 24, pl. 7, f.2, a, b,¢ (1828).—IssEL, Mal. Mar 
Rosso, p. 165. 
This species seems most nearly allied to NV. lacinulatus Couthouy. 
Guppy (Proce. Sci.-Asso. Trinidad, ii, p. 1387; Proc. Vict. Inst. Trin., 
1894, p. 123), reports it from the Gulf of Paria; but in my opinion 
his identification is incorrect. This is, perhaps, the most extrava- 
gantly ragged species of the group. 
N. cuaucus Cheeseman. PI. 43, fig. 34. 
Body from 8 to 5 inches long, about ovate when at rest, but capa- 
ble of considerable extension, a little contracted behind the head, 
then elevated, and suddenly sloping to a point posteriorly; entirely 
covered with numerous simple and branched tentacle-like processes, 
the largest of which are sometimes eight lines long. Color of the 
sides pale grayish-brown, passing on the back into a dull sea-green ; 
the whole surface with numerous irregularly shaped black blotches 
that are longest on the back. Along the back there is also a double 
row of from 8 to 12 emerald-green specks, each surrounded with a 
zone of umber. Dorsal tentacles ~ inch long, folded down the outer 
side so as to appear tubular, beset with filiform appendages. Labial 
tentacles similar in shape, but rather larger. Branchial cavity 
large, protected by the folded-in edges of the mantle, branchiz 
quite internal; foot long and narrowed, pointed behind, without 
side-lobes as in Aplysia, sole pale sea-green ; mouth roundish, placed 
under the head; odontophore with very numerous rows of simple 
hooked teeth; gizzard strengthened with large triangular calcareous 
plates ; shell none. (Cheesem.) 
Auckland Harbor, New Zealand, rather sandy localities near the 
extreme verge of low-water mark.
