Crino, Hiibncr, in the Noetuidc family Ophiusidae, which, however, 

 is rectified in the ' Stcttiner entomologische Zcitnng' for" 1862 

 (p. 477) by K. Dietrich, who regards it, and most justly, as a "N^oto- 

 dontide genus, nearly allied to the genera Fhalera, H.-Sch., and 

 Datana, Walk. 



I have seen five specimens of C'rinodes Sommeri, Hiibn. — four 

 females in the collection of the Royal Museum at Leiden (placed 

 under the name bilaminata, Do Haan, I. L., in the genus Nystalea, 

 Gn., at present also a Notodontidc genus), and one male in Mr. 

 P. C. T. Snellen's collection at llotterdam, all sent over from Java. 

 Walker (?. c. p. 1348) makes mention of a specimen from Rio Janeiro 

 in Mr. Fry's collection.

Note on lutein f/ence in Monheys. By Prof. Cope. 



I have two species of Cebus in my study, G. cajpucinus, and a half- 

 grown C. apella. The former displays the usual traits of monkey 

 ingenuity. He is an admirable catcher, seldom missing any thing, 

 from a large brush to a grain, using two hands or one. His cage- 

 door is fastened b}' two hooks, and these are kept in their places by 

 nails driven in behind them. He generally finds means, sooner or 

 later, to draw out the nails, unhook the hooks, and get free. He 

 then occupies himself in breaking up various objects and examining 

 their interior appearances, no doubt in search of food. To prevent 

 his escape I fastened him by a leather strap to the slats of the cage ; 

 but he soon untied the knot, and then relieved himself of the strap 

 by cutting and drawing ou. the threads which held the flap for the 

 buckle. He then used the strap in a novel way. He was accus- 

 tomed to catch his food (bread, potatoes, fruit, &c.), with his hands 

 when thrown to him ; sometimes the pieces fell short three or four 

 feet. One day he seized his strap and began to throw it at the 

 food, retaining his hold of one eud. He took pretty correct aim, and 

 finally drew the pieces to within reach of his hand. This perfor- 

 mance he constantly repeats, hooking and pulling the articles to him 

 in t\irns and loops of the strap. Sometimes he loses his hold of 

 the strap. If the poker is handed him he uses that with some 

 skill for the recovery of the strap. When this is drawn in, he 

 secures his food as before. Here is an act of intelligence which 

 must have been originated by some monkey, since no lower or 

 ancestral type of mammals possess the hands necessary for its 

 accomplishment. AVhether originated by Jack, or by some ances- 

 tor of the forest who used vines for the same purpose, cannot be 

 readily ascertained. 



After a punishment the animal would only exert himself in this 

 way when not watched ; as soon as an eye was directed to him he 

 would cease. In this he displayed distrust. He also usually exhi- 

 bited the disposition to accumulate, to be quite superior to hunger ; 

 thus he always appropriated all the food within reach before be-
