The Durban specimen obtained by Mr. T). R. Boyce, which I refer 

 to this species, was unfortunately devoid of the first perseopods. It 

 evidently belongs to de Man's brevivostris-growp of the genus. The 

 antennae agree with his description of the species. The third maxilli- 

 peds also agree with his account, in which he specially notes that the 

 margins of the terminal joint "are beset with long setae, those at the tip 

 being one-and-a-half as long as the joint itself." The second peraeopods 

 have the five joints of the wrist tallying well with his precise 

 measurements, which I cannot rival, but roughly it may be said that 

 the first two joints are equal and considerably the longest, while the 

 fifth is longer than either the third or fourth. The finger, however, 

 of the third perseopods is not half as long as the preceding joint, 

 in this respect differing much from de Man's account. The fifth 

 perseopod, which he does not describe, is notably more slender than 

 the third. The length of the carapace is 8 mm., and of the pleon 

 about 13 mm. 



Family HIPPOLYTTD^E. 



Genus SPIRONTOCARIS, Bate, 1 

 See Ann. S. Afr. Mus., vol. xv, p. 91; 1915. 



Spirontocaris makrognathus, sp. nov. Plate IV. 



The specimen belongs to that section of the genus in which the 

 rostrum is both short and narrow, as is the case with S. washing ton- 

 ianus, Rathbun, 1902, S. profundus, Rathbun, 1906, and by my own 

 S. pax, 1915. In the new species the rostrum scarcely extends 

 beyond the eyes, and appears to be devoid of ventral teeth. A small 

 tooth on the body of the carapace is followed by a pair of teeth nearly 

 at the base of the orbits, then by a median tooth and finally by two 

 minute teeth leading in succession to the acute apex. The specific 

 name, meaning long-jaw, refers to the striking elongation of the third 

 maxilliped, in contrast with its own diminutive exopod and with the 

 small second maxilliped, which was firmly adherent to its base. The 

 exact limits of the joints in this second maxilliped are difficult to 

 discern.
