some passing pilgrim. Among these, Cerapus abditus* is con- 

 spicuous from his powerful claws. 



Dercothoe (Cerajms) pundatus, now supposed to be the female 

 of the preceding, will be seen in another such nest; a small one, 

 from its spotted appearance and the form of the gnathopod, 

 aj)pears to agree with C. difformis, if it is not the young of the 

 preceding. In similar situations Fodocerus pulchellus and P. 

 pelagicus also occur ; sometimes the nest is formed on the old shell 

 tenanted by a hermit-crab. There we find also his companions, 

 Nmiia rimcvpcdmata and N. excavafa. From the shore T add also 

 AmphitJioe Uttorina, as another example of a nest-builder. 



In the muddy refuse at the bottom of a bucket, into which 

 some Ascidians, muddy shells, and other animals had been thrown 

 in the course of dredging, there occurred a beautiful Amphipod, 

 distinguished by " a blush of rose colour," with crimson spots on 

 some of the limbs, particularly on the anterior portion of the body, 

 Ampelisca Gaimardii. One striking peculiarity in this genus 

 consists in the eyes being formed of only two simple lenses on 

 each side of the head, with a small mass of pigment behind them. 

 I am not certain whether they were brought up in some of the 

 mud hauls, as they were not observed at the time, and only three 

 specimens were got. [In the mud off Ashton I have taken Anomjx 

 ampidla in considerable numbers, and a few of A. denticulatus along 

 with them.] 



In the Bay I have also obtained Gossea microdeutopa, Aora 

 gracilis, Gammarus marinus, UrotJioe elegans, Calliope IcBviuscula, 

 Montagua monocidoides. The three last were also obtained in 

 1859, and most probably with the towing net. They have been 

 preserved in glycerine, and still retain their colouring — Montagua 

 its red eye, and Urotho'e its pink markings. At that time I also 

 obtained another curious species, the pleon of which has a deep 

 notch, and terminates abruptly with a straight outline, so that 

 the telson seems as it were to be stuck on to the truncated pleon. 

 The last pereiopod has also a large coxa beautifully cancellated in 

 honey-comb pattern, and the propoda are hairy on both sides. 

 This species does not seem to have been known till after the 

 publication of Spence Bate and Westwood's work, when it was

 Bate and Westwood's " Sessile-eyed Crustacea." Lon., 1863.
