34 Mr. Lubbock on 



Sapphirina slylifera, n. sp. 



Digitus antennarum posticarum tenuis, carpo fere duplo lon- 

 gior. Lamellae caudales longae, latitudine '002, longitudine 

 •025 unc. 



This species may at once be distinguished from any other by 

 the length and narrowness of the caudal stylets. I had only two 

 specimens, neither of which were in a very good state of preserva- 

 tion, and I could not determine with certainty whether the con- 

 spicilla were contiguous or not. 



Collected in N. L. 12° 21' ; W. L. 25°. 



PI. IV. figs. 9, 10. 



Helocypris Atlantica, n. sp. 



Forma Conchceciam refert, latere visa, literae D elongatae for- 

 mam similis, postice paulo altior, margine supero recto, in- 

 cisurd mediana, antico et infero leniter arcuato, postico ob- 

 liquo, inferne rotundato, superne angulato, ad apicem obtuso. 

 Superne visa, C. agili angustior. 



This species appears to be somewhat intermediate between the 

 genera Conchcecia and Halocypris, In external form it more re- 

 sembles the former, but the structure of the anterior antennae and 

 the mandibles proves that it in fact belongs to the latter. 



The anterior antenna (PI. XII., fig. 3) differs from that figured 

 by Dana in consisting only of one segment. The hairs belonging 

 to it were all imperfect, except two. I only had two specimens, 

 and did not succeed in detaching the maxillipeds uninjured. The 

 figures are magnified thirty times, except figs. 1 and 2, which are 

 magnified only fifteen times. 



Length -086. 



Collected in N. L. 12" 21'; 25° W. 



PI. XII. firrs. 1 to 8.
