The liabits and special habitats of some of the sessile-eyed Crustacea are noticed. Acknowledg- 

 ment is made to Mr. Spence Bate and the Rev. A. M. Norman for assistance in determining 

 doubtful forms. In the list of Amphipoda, AUorchestes nihsonii of Bate and Westwood is 

 transferred to " Hyale Nilssoni, H. Ratlike;" the spe,cies monoculoides, Mont., marina, 

 " Alderi," pollexiana, dypeaia, assigned to Monfagua by Bate and Westwood, are here 

 referred to Stenotlwi', Dana; their Anonyx denticulatus to Anonyx holboUii, Kroyer, their 

 Ampelisca gaimardii to Ampelisca carinata, Bruzelius, their Ampelisca belliana to { = A. 

 macrocephala, Lilljeborg ?). " CaUiopms btdentatufi (n. sp.), Norman, Nat. Hist. Trans. 

 Northumb. & Durham, vol. i. 1865, p. 24," said by Mr. Norman to be not uncommon all 

 along the east coast, is thus described : — " The body J0 about two-fifths of an inch long, of 

 a pale straw colour, tinted with brownish at the joints and the bases of the limbs. 

 Superior antenn<e twice as long as the inferior, beautifully banded with red. Eyes 

 irregularly rounded, brownish red or pale brick-red. The first and second gnathopods are 

 nearly equal (the second, however, being larger) and similar in structure. Hand almond- 

 shaped, the palm being furnished with a series of very distinct stout spines, and a row of 

 smaller spines reaching the base of the finger ; the latter is long, boldly curved, and 

 regularly divided on the concave side. The first and second pleopods [? pleon-segments] 

 have spines, that of the former, however, being sometimes indistinct. A very characteristic 

 convexity occurs at the junction of the third and fourth pleopods [? pleon-segments] ; and 

 the dorsal margin of the latter is concave." 



Eiscludus longicaudatus of Bate and Westwood is here given as Heiscladius longieaudatus, their 

 Amj)ldilwe lUtorina as Ampliitlwe p>t>doceroides, H. Eathke, and distinct from Amphithoe 

 ruhricata, Mont. " Most of the fine specimens," it is said, " have the hand of the second 

 pair defined by a distinct tooth, as Rathke and Dr. Johnson state." Podocerits falcatus, 

 Mont., is given as including Podocerus pulchellus and Podocerus pelagiais of Bate and 

 Westwood, Podocerus variegatus, Leach, as including their Podocerus capiillatus. 

 " Siphonoecetus Whitei," Gosse, is said to be probably the female of " Siphonoecetus 

 typicus," Kroyer. The three species, tuberculosa, rimapalviata and excavafa, assigned by 

 Bate to Nxtiia, are all recorded as found together in the " debris from the coralline ground." 

 Hyperia medusarum, O. F. !Miiller, is given as including Hyperia galba of Bate and 

 Westwood, with the remarks " The Lestrigonus Kincdiani, Bate, is a sexual variety (male). 

 Some large specimens are found swimming freely on the surface of the water." " j^gma 

 pliasma, Mont. ; B. & W. op. cit. ii. p. 45," appears without notice that the authors quoted 

 do not asoign it to ^gina. " Caprella iuherculata, Guerin ; B. & W. op. cit. ii. p. 68," is 

 said to be common on Ceramium ndn-um in rock-pools, and in the stomachs of cod and 

 haddock. Mr. Norman's opinion is given that the Caprella hystrix of Bate and West- 

 wood is not the Caprella liystrix of Kroyer, but rather is Caprella septenlrionalis. The 

 list includes several other Amphipoda, with occasional notes on colouring.
