pair of pcmopoda rosi'ml)linsj: tho first, b»it havinf» tlio carpus 

 longer ami tlit> intorior angle not so prominent. Third pair having 

 the carpus with the anterior margin .subparallel with the poste- 

 rior : anterior margin oblicpie, serrated with four large and two 

 small teeth ; tooth of inferior angle largest and outwardly directed. 

 Fourth pair of pereiopoda lla^■ing the meros Anth the antero-distiil 

 angle produced a.s long as the carpus; car])us long, gradually in- 

 creasing in diameter, antero-distal margin denticulated and pro- 

 duced towards the inferior angle ; tooth of the inferior angle con- 

 siderably the longest, directed straight foi-w^ard ; anterior margin 

 of the united propodos and dactylos rugose. 

 Length | an inch. 



Huh. Found in the stomach of a shark, lat. 26° 27' S., long. 99° W. 

 In all other respects this species resembles the preceding. 



Doubtful Sjiedes. 



4. Phrosina macrophthalma, 



Phrosina maerophthalnia, liisso, Joiini. de Phys. Oct. 1822, p. 245. 

 Desmaresf, Consid. sur les Crust, p. 25. 



" Body oblong, of a violet-red, having the eephalon ver}' transparent, 



not homed. Ej^es very large, oval, and black. 

 *' Length about 3 lines. 



" Hah. Found by Risso on Pi/rosoma eler/ans, in February and July. 

 In the latter month the female carries a great numljer of very small 

 globular eggs." — Desmarest. 



This species probably belongs to the genus Anchyhmera.

Superior antenna; as long as the eephalon. Inferior antenna) ob- 

 solete. Gnathopoda not subchelate, nor very small. First two 

 pairs of pereiopoda having the carpi not dilated ; third pair twice 

 as long as the preceding, and haring the carpus largely dilated 

 and armed, propodos and dactylos not fused together ; fourth pair 

 considerably smaller, not having the ctu-pus dilated ; fifth pair 

 much smaller. Three posterior pairs of ploopoda consisting each 

 of a uuiarticulate membranous lamella. Telson single. 



This genus is distinguished from Phrosina by the smallness of 

 the first two pau-s of pereiopoda, the developed chai-acter of the fifth 

 pair, and in ha\-ing the dactyla not fus(>d with the propoda.
