REPORT ON THE AMPHIPODA. 565 



definition of Li/sianassa. To Eusirus duhius, Haswell, he adds the account of a variety, 

 ])1. xiv., fig. 1, and a new species, Eusirus affinis, pi. xiv., figs. 2-4. Irom the information 

 given I am inclined to group all three forms with one described in this Report under the 

 name LiJJehoiyia hasKdli. It -would not, I think, be reasonable to transfer the specific 

 title (hthius, which was applicable enough in connection with the generic name Eusirus, to 

 the undoubted position of the new species in the genus Liljehorgia. In the Uritish Museum 

 Catalogue by some accident the telson in this genus is said to be entire, a mistake corrected 

 in Bate and Westwood's subsequent work. Probably Mr. Haswell's attention was diverted 

 from the genus Liljehorgia, when he found the telson in his own species cleft almost to 

 the root. He accepts the view of Miers that Leucothoe commensalis is a variety of 

 Leucotlwc spinicarpa, and states that Leucoihoe gracilis and Leucothoe diemenensis are to be 

 regarded as marked varieties of the same. He describes a new species under the name 

 Attjlus liornocliir, pi. xiii., figs. 5-7, which will also be found described and figured among 

 those brought home by the Challenger. " De.cavmie iliersii," n. s., pi. xiii., figs. 8-12, is 

 described. Figures, pi. xv., figs. 1-4, and description are given of "a species from Port 

 Stephens which is very nearly related to Megammra suensis, and yet differs from it in 

 several particulars." "This species bears a considerable general resemblance also to Mwra 

 hamigera, but the modification of the left posterior gnathopods in this latter species is 

 so special as to distinguish it very clearly." Megcmicera tltomsoni, Miers, is identified with 

 Megamoira mastersii, Haswell. Mcera spinosa, Haswell, Mara ramsaiji, Haswell, and Mcera 

 /estiva, Chilton, are identified with Mcera rulro-maculata, Stimpson. To this list of 

 synonyms must no doubt be added Megamwra serrata, Spence Bate. Mr. Haswell speaks 

 of " the form figured by Stimpson," but without saying where the figure is to be found. 

 Fresh figures are given of Xenoclieira fasciata, Haswell, pi. xvi., figs. 1-3, with the remark 

 that " in most of its characteristics this species shows evident relationships with Mirro- 

 deuteroxjHs. In fact it is only the form . and proportions of the gnathopoda (figs. 1 and 2) 

 that separate it from the normal members of that genus, with which it is connected 

 through the European M. versiculatus, Spence Bate." Of Haplocheira iijpica, pi. xvi., 

 figs. 4-8, Mr. Haswell writes that its relations are rather with the Podocerides than with 

 the Gammaridse, " the last pair of pleopods being short, with slightly hooked spines on the 

 outer ramus, and a very short inner ramus with a simple pointed spine, and the telson 

 (fig. 8), being a small undivided plate with a strong hook at each of its postero-lateral 

 angles." He says further, " the superior antennae have small two-jointed appendages — a 

 feature which I overlooked in my first examination. The flagellum of the inferior antenn;e 

 has three distinct joints. The anterior gnathopods (fig. 4) might be described as very 

 imperfectly subcheliform — the propus having a small lobe at the base of the dactylus. The 

 nearest ally of the genus seems to be Coropidum, and C. Lendenfeldi of Chilton (Trans. 

 N. Z. Inst, etc.) is probably this species." Ganimarus harhimanus, Thomson, 1879, takes 

 precedence as Haplocheira barbimanus. Of Harmonia crassipes, Haswell, pi. xvi., fig. 9, 

 he writes, " The relations of this species were not correctly expressed by the position in 

 which it was placed in the ' Catalogue of Australian Crustacea.' It is a member of the 

 family Corophiidee, distinguished from Amphithoii, Sunamphithoi: and Nania, among other 

 points, by the presence of an appendage on the superior antenna, from Cerapus by the 

 biramous character of the posterior pleopoda, and from Podocefrus by the multi-articulate 

 flagella of both pairs of antennae. The genus may be defined as follows : — Coxaj not so 

 deep as the corresponding segments ; antenna; both with multi-articulate flagella, the superior 

 pair with an appendage. Mandibles palpigerous. Maxillipedes unguiculate, sub-peditbrm, 

 with a squamiform process on the basos only. Gnathopods sub-chelate, unequal, posterior 

 pair very large. Posterior pleopods biramous, the outer ramus with slightly hooked spines 

 and straight hairs, the inner with straight hairs only. Telson single, long, pointed." From
