CYCLOPOIDEA. -J153 



Collected in the Pacific, six miles north of Upolu, one of the Samoan 

 Islands, February 24, 1841 ; also, near El Gran Cocal, March 25, 

 1841, latitude 5i° south, longitude 175° 45' east. 



^ Length, one-fifteenth of an inch. Colour, pale reddish with green- 

 ish along the intestine. The acute extremities at the posterior part 

 of the cephalothorax appear to belong to a fourth posterior segment, 

 of which only this part is seen. Counting this as one, there are seven 

 segments to the cephalothorax. The above character, in addition to 

 the rather long stylets, the bilobate pigment (deeply indented behind) 

 of the inferior eyes, and the characters of the two pairs of antenna 

 (the anterior shorter than the cephalothorax), serves. to distinguish the 

 species. The beak has the usual character. The fourth and fifth 

 joints of the anterior antennae are much longer than those immediately 

 preceding or following. A seta on the tenth or eleventh joint from 

 the extremity is longer than the others near by. The setae of the 

 longer branch of the posterior antennae, when thrown back, extend as 

 far as the fifth segment (out of the seven) of the cephalothorax. 



PONTELLINA EMERITA. 



Feminae: — Crassa. From obtusus. Cephalothorax 6-7-articulatus, 

 capife discrete, angiitis posticis elongate acntis, segmento postico brevi. 

 Oculi superiores re?noti, inferiores sat parvi. Antennce anticce cepha- 

 lothorace vix longiores, ferml 100° divaricatce, rectce. Ramus major 

 antennarum posticarum fere quadruplo longior. Styli caudales breves. 

 \_Abdomen 2-articulatum, segmentis subcequis^] 



Female: — Stout. Front obtuse. Cephalothorax long and remotely 

 acute behind, six- to seven-jointed, head separate, posterior joints 

 four, the last short. Superior eyes remote, inferior rather small. 

 Anterior antennae scarcely longer than the cephalothorax, divergent 

 100° to 110°, straight, setae short. One branch of the posterior 

 antennae hardly one-fourth the other in length. Caudal stylets 

 short, setae of moderate size (rather short), much spreading. [Ab- 

 domen two-jointed, segments subequal.]
