Zoological Notes from Aneiteum. 7141 



A solitary Aulastoruus, which sometimes measures above a yard in 

 length, represents the Fistularidae. 



The Order Malacopterygii does not, apparently, contain many Anei- 

 teumese fishes. Belone, Hemiramphns, Exocetus and Plotosus are 

 the only abdominal ones I know of. The last is carefully handled by 

 the fishermen on account of the barbed spines, of which there is one 

 in the first dorsal and each of the pectoral fins. A Phycis belongs to 

 the first, and a Pleuronectes to the second section of the Subbrachiate 

 Order. The Phycis alluded to may perhaps belong to another genus, 

 as its ventrals consist of two rays each, instead of a single one. The 

 fishes of the third section, or apodous Malacopterygians, are an Anguilla, 

 common in the fresh water, and three or four species of Murgena, 

 Ophisurus and allied genera. 



The only Lophobranchiate fishes I know of are two kinds of Syng- 

 nathus. 



The first or Gymnodontal division of the Plectognathi is represented 

 by a fine large Tetraodon, covered, except, on the belly, with white 

 spots, and a Diodon with long spines directed backwards, with the 

 exception of a few of the foremost ones. The second or Scleroderma! 

 division contains as many as seven species of Balistes, the most 

 singular of which has numerous large, white, eye-like spots, and two 

 kinds of Ostracion very closely resembling each other. 



Of the cartilaginous fishes there is only one representative in the 

 collection, a young Carcharias, probably C. melanopterus. Sharks, 

 however, are not uncommon, and I have also seen at least one species 

 of Trygon. 



Description of Prisopus Carlotta, a New Species of Leaf Insect. 

 — Female. Body much depressed, slightly convex above, flat 

 below ; whole of upper surface and membranes rugose, also with small 

 tubercles on the body, especially the thorax ; lower surface smooth. 

 Antennae setaceous, nearly half as long as the body, of about twenty- 

 five joints. Wing-covers their own width apart, very small (little more 

 than one-tenth of an inch in length), rounded on outer and posterior 

 edges, and straight on internal margin ; wings also very small, when 

 folded reaching the middle of the first abdominal segment, and pro- 

 jecting the tenth of an inch behind the covers. Abdomen of ten 

 segments, slightly widening from the base towards the middle, then 

 tapering to the extremity, with a faint central dorsal ridge above, and 

 two lateral ones on the lower surface ; a minute lateral appendage 

 behind the fore legs, and four pyriform plates on each side between
