the body, the form of the 2 posterior pairs of legs and of the telson." 42. Harpinia 

 mucronafa, " distinguislied by the strong, hook-shaped point formed posteriorly by the 

 lateral plates of the 3rd abdominal segment, as also by the very peculiar form 

 characterizing the basal joint of the last pair of legs." 43. llarinnia serrata, very near 

 to Harpinia pluviosa, Krciyer, but distinguished by " the anterior abdominal segments 

 being densely pubescent above," and by the serrate basal joint of the last pair of legs. 

 Gen. 3. UroiJioe, Dana, 1852. 44. Urofhoe abhreviata, length, 3 mm., " easily recogniz- 

 able by its remarkably short and thickset body, the peculiar form distinguishing the first 

 pair of antennfe, the absence of eyes, and by the short last pair of caudal stylets." 



Fara. 3. Epimeridse. Gen. 1. Epitneria, Costa, 1851. 45. Epimeria loricata, "Colour a 

 gorgeous red. Length reaching 40 mm., distinguished from Epimeria comigera, Fabr., 

 by " size, remarkably firm integuments, and the deviating armature of the body. Gen. 2. 

 Paramphitho'e, Bruzelius, 1859. 46. Paramphitho'e euacantha, " Phustes euacantus [eua- 

 cantlnin], G. 0. Sars, Prodronius Crust, et Pycuog. etc.. No. 110.," "approximates very 

 closely P. pulehella Kroyer, but is easily recognized by the thoracic segments, including 

 the 3 anterior ones, being all of them keeled and running out as dorsal projections, 

 whereas in the former species this is the case with the posterior ones only. Moreover, 

 the form of the 2 anterior pairs of legs differs somewhat. The genus Paramphitho'e is 

 referred by Boeck to the family Oedicerinse. In my judgment it should rather be classed 

 among the Epimeridfe. Furthermore, I have seen fit to retain Sp. Bate's genus Pleustes 

 for P. pa7iop)la, Kroyer, and the species nearest related to that form." Sars is here 

 referring to Boeck's work of 1870, for in his posthumous volume, 1876, ParampihUhoe, 

 as limited by Boeck, is made a synonym of Plemfes, Sp. Bate, included indeed among the 

 Oedicerinae, but with the remark, " Genus Pleustes ad subfamiliam Oedicerinse vix referen- 

 dum est." 



Fam. 4. Oediceridre. Gen. Oedicews, Krojer, 1842. 47. Oediceros macrocheir, to be "recog- 

 nized by the remarkably small and non-inspissated frontal projection, the absence of eyes, 

 and the prodigious development characterizing the 2 anterior pairs of legs." 



Fam. 5. Atylida3. Gen. Haliraijes, Boeck, 1870. 48. Halirages qvad ridentaius, very near 

 Haliraijes fulvucincius, M. Sars, but distinguished by size, length 24 mm., "greater 

 number of dorsal spines, and the deviating form and armature of the lateral plates of the 

 3rd abdominal segment." Gen. 2. Cleippides, Boeck, 1870. 49. Cleippides qvadrimspis. 

 Heller, total length of specimens reaching 52 mm., the antennjc not included. Gen. 3. 

 Amphithnpsis, Boeck, 1860. 50. Aviphitliopsis piulchella, nearest Amphithopsis latipes, M. 

 Sars, but " distinguished by a less thickset body, the absence of a dorsal keel, less robust 

 ambulatory legs, as also by its colour. Moreover, the form of the 2 anterior pairs of legs is 

 rather different." 



Fam. Gammaridse. Gen. 1. Maera, Leach, 1813. 51. Maeva tenera, " Maem tendia, G. 0. Sars, 

 Prodromus descriptionis Crust, etc.. No. 119 (non Stimpson)," "distinguished by its 

 remarkably slender body, the evenly rounded 1st pair of epimera, the total absence of eyes, 

 and the linear form of the basal joint of the 3 posterior pairs of legs." Gen. 2. Mclita, 

 Leach, 1813. 52. Melita pallida, "posterior margin of all abdominal segments, with 

 exception of last, jutting out above as 2 flat, appressed spines, from between which rise two 

 or three considerably smaller one. Lateral plates of 3rd segment produced posteriorly to a 

 sharp point. No eyes." Gen. 3. Amathillopsis, Heller, 187 5. 53. A»/afhillopsi!< gjmir/era, 

 Heller, " length of largest specimens reaching 50 mm." 



Fam. Syrrhoidse. Gen. Bruzdia, Boeck, 1870. 54. Bruzdia serraia, distinguished from 

 Bruzelia iijinca, Boeck, "by the sharply-marked dorsal keel, with its high, compressed 

 projections, as also by the posteriorly serrate lateral plates on the 3rd abdominal segment." 



Fam. Stenothoidse. Gen. 1. Metopa, Boeck, 1870. 55. Metopa siKdahilis, "length reaching
