14 Mr. Lubbock 



C. inconspiaius, n. sp. 



Frons rotundata. Cephalothorax 5-articulatus, crassus, postice 

 obtusus, superne visus angulis acutis, segmento postico brevi. 

 Antennae anticae corporis longitudine, setis brevibus, apica- 

 libus arliculum aequantibus und longiore ; subapicalibus ini- 

 nutis. Maxillae et maxillipedes ut in Calano. Pedes nata- 

 torii primi paris ramis 3 et 1-articulatis, quarti paris ramis 

 ambobus 3-articulatis. Abdomen 5-articulatum breve. Setae 

 caudales quatuor, subaequae. 



If all my specimens are females, which the form of the abdomen 

 seems to render probable, this species may, perhaps, be an i/n- 

 d'lna. 



The anterior antennae are "065 in length. At the apex there 

 is one rather long hair, and two others rather longer than the 

 apical segment ; the penultimate and ante-penultimate hairs are 

 very minute, and all the rest are small. 



The second pair of antennae are •01.'5 in length. The accessory 

 branch is about one-fourth longer than the organ itself, and the 

 intermediate segments are indistinct ; the basal segment of the 

 shorter branch has the margins very straight, and is of equal thick- 

 ness all the way up ; there are six hairs at the apex in one tuft, 

 and seven in the other. 



The maxillipeds are of the usual form, and are '02 in length. 



The first pair of natatory legs are "015 in length, the outer 

 branch has three segments, the inner only one. The inner branch, 

 and the apical segment of the outer branch, have two hairs at the 

 side and two at the apex. The spines on the outer margin are 

 inconspicuous. 



The fourth pair are "025 in length. The branches are both 

 three-jointed, the two basal segments of each branch have a hair 

 at the apex, the terminal segment of the lesser branch has two 

 hairs on the margm and two at the apex ; that of the larger branch 

 has three at the margin and two at the apex. The fifth pair of 

 legs appears to be wanting. 



The abdomen is 5 jointed; the first and second segments are 

 swollen. The stylets are short, and the four terminal hairs sub- 

 equal in length.
