OF FISH OBTAINED AT PLYMOUTH. 163 



upon the back of the cephalothorax, and has been described by 

 Milne Edwards. 



Var. parva ? Very frequently a smaller animal was also found on the 

 same fish, in like positions, apparently differing only in not having any 

 secondary lobular prolongations on the arms. They had the three pairs 

 of horn-like processes posteriorly, and the males appeared identical ; but 

 as they bore egg sacs, they might be specifically difl'erent. 



4. Brachiclla bispinosa, Nordmann. Found in quantity from Trigla 

 cucuhis, T. garnardus, T. lyra. Attached to the gill rakers of the outer 

 branchiie ; rarely more than two on each fish. The head has the same 

 characteristic organs as in B. impudica. The male, which is found at 

 the back of the cephalothorax, has also equal resemblance. 



5. Brachiella triglcv ( Anchorclla triglcv, Claus). This species is found 

 attached to the gills of the various Gurnards, T. cucidus, gurnardus, and 

 Mrundo, but was not very common. Although in its outward form the 

 female has most of the characteristics of an Anchorclla, the male dis- 

 tinctly shows it to belong to this genus. 



6. Brachiella 7nerluccii, n. sp* These animals are always found 

 attached to the points of the gill-rakers of the Hake, Oadus raerluccius, 

 and never attached to the gill rays themselves, as B. insidiosa. Both 

 were frequently found in the same fish, but their positions were never 

 other than that noted. 



Anchorella, Cuvier. 



Second pair of maxillipedes short, united together, ending close to 

 their origin, in a fixing organ. (Male showing no trace of segmentation 

 of the body, which is not elongated, but globular. B.-S.) 



1. Anchorella emarginata, Kroyer. This species was found attached 

 to the gill-rakers of the outer branchiie of Glupea alosa. The second pair 

 of maxillipedes are not completely united at their base. 



2. Anchorella paradoxa, Van Beneden. Found on the gills of Scomber 

 scomber, but rare. The species is, however, very characteristic, and the 

 male is distinctive, but has not yet been described by any author.* 



3. Anchorella uncinata, Muller. This species is extremely common, 

 being found in the folds of skin around the mouth, and in the gill-cavity 

 of cod, haddock, pollock, whiting, and whiting-pout. The organ of 

 adhesion of this species is a perfect drill. 



4. Anchorella quadrata, n. sp* A few specimens were obtained of 

 this species from the Dragonet, Callionynms lyra, attached to the gill 

 rakers. This species is much like Anchorella falax. Heller, in form, 

 except for the great size of the abdomen.
