A specimen of the male dredged at Salcombe has one of 

 the second gnathopods normal, the other much smaller and 

 almost without trace of denticulation. A specimen of Melita 

 palmata taken at Torquay presents a similar inequality in the 

 second pair of gnathopods. Another example of M. palmata 

 in the same condition has been described by Mr. Spence Bate ; 

 who suggests in explanation that a limb has been lost by some 

 injury, and then replaced by a new one imperfectly developed. 

 These casualties would seem to argue a combative disposition 

 in the genus Melita, 



Proto Goodsiri, Spence Bate. 



As in the ' British Sessile-eyed Crustacea ' Proto Goodsiri 

 is thought to be only a northern species, it may be worth while 

 to record its capture in the Salcombe estuary during August 

 of this year (1875) . The work just mentioned affirms that '' the 

 tail is very rudimentary, and supports in the male a single 

 pair of rudimentary propoda." In the Salcombe specimens, 

 however, there are two pairs of these styliform appendages, 

 as in the closely allied species Proto j)&d<:tta. Both species 

 Avere dredged in the same part of the estuary ; and the female 

 forms, found in proximity to each among the contents of the 

 dredge, were not distinguishable from one another. 



The numerous variations in the second gnathopods oiCaprella 

 acanthifera make the suggestion at least plausible that Proto 

 ■pedata and P. Goodsiri^ mainly distinguished as they are by 

 differences in the hands of the second pair, may be only varieties 

 of one and the same species, with P. Goodsiri for the older, as 

 it seems to be invariably the larger, form. 



Tanais vittatus, Lilljeborg. 



In discussing the genus Ajosetides, Messrs. Bate and West- 

 wood take occasion to remark that, although they had examined 

 some hundreds of individuals of the genus Tanais, they had 

 never seen one possessing the features of a female. At the 

 same time they call attention to Eathke's figure of his Gros- 

 surus vittatusj wath a large incubatory pouch filled with large 

 eggs, this Crossurus being the Tanais of Lilljeborg. They 

 mention also that Milller, Eathke,and Lilljeborg have described 

 the females of Tanais as resembling the males. Additional
