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. (Riippell).

 !N6rdlichen Afrika von Eduard Riippell, Neue Wirbellose Thiere 

 des rothen Meers, p. 24, pi. 7, f. 2, a, b, c (1828). ISSEL, Mai. Mar 

 Rosso, p. 165. 



This species seems most nearly allied to N. laeinulatus Couthouy. 

 Guppy (Proc. Sci. Asso. Trinidad, ii, p. 137 ; Proc. Viet. 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. GLAUCUS Cheeseman. PL 43, fig. 34. 



Body from 3 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 f 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, branchiae 

 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.
