REPORT ON THE AMPHIPODA. 787 



Remarks. — The specific uame was given in lionoui' of the kite W. Wilson Saunders 

 Esq., F.R.S. 



There seems little reason to doubt that this is the same species as that described in 

 the Annals and Magazine of Natural History for March 1875. The specimen originally 

 figured was obtained from a collection of sponges and other marine objects which had 

 been gathered partly in Algoa Bay, South Africa, and partly from the neighbourhood of 

 Swan River, West Australia. As the various objects had been packed together, small 

 specimens might easily have been shaken out of one into another, and therefore the 

 proper habitat to assign to such small specimens would become a matter of uncertainty. 

 Teraticum typicum, described by Mr. Charles Chilton in 1884, must, I think, be identical 

 with the present species, and from his figures it may be inferred, as he suggests, that the 

 first gnathopods of the two sexes differ greatly, if we may presume that his figures ih, 

 Ic represent the first gnathopod of the male. In his account of the antennsB, Mr. 

 Chilton gives " first joint of upper antenna equal in length to the second, but stouter," 

 whereas in the specimen described in 1875 the second joint is a little the longer, and in 

 the specimen here described decidedly longer. 



Family Syrrhoid.e, G. 0. Sars, 1882. 



In 1870 Boeck established the Syrrhoinse as seventh subfamily of the Gammaridse; 

 in 1876 he made it the fourth subfamily of the Leucothoidfe ; in 1882 Sars changed 

 the subfamily into a family without alteration except in the form of the name. The 

 genera assigned to the group alike by Boeck and Sars are Syrrhoe, Goes, Tiron, Lillje- 

 borg, and Bruzelia, Boeck. Boeck gives the following definition : — 



" Upper Lip broad, apically insinuate. 



" Mandibles very strong, broad ; the pair not uniform ; the left mandible furnished 

 with an inner accessory process ; the palp three-jointed, with the last joint very 

 short. 



" Loioer Lip broad. 



" First Maxillm with the inner plate broad, setose ; the palp two-jointed, narrow, 

 generally furnished apically with few setae. 



" Second Maxillie with broad plates. 



" Maxillip)eds with the outer plates very large, armed with strong teeth on the 

 inner margin ; the inner plates broad, long ; the palp broad, short, or more elongate. 



" The body more or less sub-depressed ; the head large ; the side-plates of moderate 

 size. 



" The Eyes often approximate and coalesced. 



" Upper Antennae with an accessory flagellum.
