484 THE VOYAGE OF H.M.S. CHALLENGER. 



chelifera, Sp. Bate, the male is figured and both sexes are described. The female is said to 

 bear a close resemblance to that of Aora gracilis and that of Microdeutopus anomalus. 

 Of the genus Callimerus, Stebbing, the following characters are given : — 



"Antennfe subequal; superior antennre without secondary appendage; first pair of gnathopods 

 simple ; second pair having the carpus infero-anteriorly produced, the coxcB of the second 

 pair covering those of the first. Penultimate pleopoda shorter than either of the other pairs. 

 Telson simple." This genus is a synonym of Amphiloclnis, Sp. Bate, the maxillipeds 

 having given rise to the description of the first gnathopods as simple.

" AmpJiilocJius Sahrinm," n. sp., is figured and described. It is very like AmpMIocJius hispinosus, 

 Boeck, but the second side-plate is not serrate as in Boeok's species, having only a single 

 indentation. The two first segments of the pleon have not a dorsal tooth, and in the last 

 uropods the rami are very much shorter than the peduncle, instead of being only slightly 

 so. There are other minute differences, but not such as I should venture to rely on without 

 an examination of fresh specimens. I am aware also that in creatures whose full size is 

 one-twelfth of an inch, the presence of the dorsal teeth on the pileon may sometimes be 

 overlooked. 



This paper contains the remarks on AmpJiilochus coneinna and Callimerus acudigitata, which 

 have been already referred to. 



Under the name Podoceropsis intermedia, a species is described as new, which is no doubt a 

 synonym of "Podoceropsis SopMx," Boeck, 1860. 



An additional note mentions various " Amphipoda in Sponges."

The collection described was made by Surgeon William H. Jones, U. S. Navy, according to 

 whose experience night is " about the only time when surface dredging can be carried on 

 with any prospect of success." Dr. Streets gives a definition of the Oxycephalidse, and in 

 a note observes, "Glaus classifies the Oxyceplialidae along with the Phronimidee in his 

 family Plironimides, and states that the mandibular palpus is absent, which is an error. 

 Though absent in both sexes of the Phronimidx, it is present in the male of the 

 Oxijcephalidse." (On these points see Notes on Glaus, 1879.) Descriptions and (small, 

 inadequate) figures are given of Oxijcephalus tubercidatus, Sp. Bate, which Glaus identifies 

 with O-rijcephaliLs piscator, M.-Edw. ; of Oxycephalus hulhosus, n. s., taken between Lat. 

 28°00 and 35-45 N., Long. U0°00 and 141°25 W., and given doubtfully by Glaus in 1877 

 as a synonym of his own Oxycephalus tijplwides, 1879, from Zanzibar and Messina; of 

 Oxyceplialus scleroticus, n. s., which shares with Glaus' Oxycephalus fyphoides the peculiarity 

 of having " on the fifth ejjimeral a jjrominent spine, directed backwards " ; and of Leptocotis 

 spinifera, Streets, 1877. The new genus Calamorhynclms is thus defined :• — "Body elongated, 

 slender, almost rod-like. Head large, dejiressed, produced anteriorly to the eyes in a broadly-
