Ttiis inaportant work gives in the Introduction a general account of the structure of the 

 Amphipoda. The accounts of Sir. Haswell's own species are reproduced from his earlier 

 publications already noticed. Among the addenda et corrigenda at the end of the volume, 

 he remarks tliat "the species on which the genus Neoliule was founded belongs to the 

 Orehestiilx, and is allied to the form afterwards named by me Aspidoplioreia." He had 

 previously placed Neohule in the subfamily Stegocephalides. The name Glycera is now 

 altered to Ghjcerina, Ghjcera being preoccupied. The species Icilius pundatus is recognised 

 as only a variety, and therefore a synonym, of Icilms australis. ,

Crangonyx lucifiigiw, n. sp. " a small, rather elongated species, that was obtained from a well in 

 Abingdon, Knos county, Illinois," " appears to resemble C. tenuis Smith, but is evidently 

 different. In that species, as described by Prof. S. I. Smith, the first pair of feet are 

 stouter than the second, and have the palmar margin of the propodite much more oblique. 

 The reverse is true of the species I describe. Nor do I understand from the description of 

 C tenuis that the posterior caudal stylets each consist of a single segment. There are 

 some minor difl'erences. From C. vitreus, judging from Prof. Cope's description in 

 American Naturalist, Vol. vi. p. 422, it must differ in the caudal stylets. ' Penultimate 

 segment, with a stout limb with two equal styles,' is a statement that will not apply to my 

 species, whichever the 'penultimate' segment may be." 



ilr. Hay nfext describes " Crangonyx hifurcus, n. sp. — General form and appearance those of the 

 Western variety of C. gracilis." "This species," he says, "differs from C. gracilis more 

 particularly in the form of the telson, and in the length of the outer ramus of the posterior 

 stylets as compared with the peduncle. From C. antennatum Packard (American 

 Naturalist, 1881, p. 880), it differs in the form of the telson, and in the much greater 

 size of the eyes." Found in a rivulet at Macon, Miss. "The three species, C. gracilis, 

 C. hifurcus and C. luci/ugus present an interesting gradation in the form of the posterior 

 caudal stylets. In the first-named the outer ramus is twice the length of the peduncle, and 

 the inner ramus is present, but rudimentary. In C. hifurcus the outer ramus is but two- 

 thirds as long as the peduncle, while it is doubtful whether there is anything whatever 

 to represent inner ramus. In C. Iwifugus both the outer and inner rami arc absent, and 

 the peduncle itself is much reduced."
