of the genus Laophontodes was noted, as also its material difference from those 

 species as regards the structure of the 1st pair of legs. 



Occurrence. I have been long acquainted with this remarkable form, 

 which I have come across in many different places on the Norwegian coast, though 

 always quite by chance. It is found in depths ranging from 16 to 30 fathoms 

 and, as noted by Norman, generally in places where otherwise animal life 

 proves to be very scanty. The specimens are generally so thickly covered 

 with muddy particles adhering to the numerous curved processes of the body, 

 that it is rather difficult at first sight to obtain a correct idea of their true 

 forms and wonderful armature. They move through the water in a somewhat 

 jerky manner, and never for long together. 



Distribution. Scottish coast, at Cumbrae (Norman). 



Gen. 68. EeMnOpSyllUS, Gr. O. Sars, n. 



Generic Characters. Body provided with dorsal and lateral projections, 

 but wanting a sub-dorsal series. Rostrum very small, but well defined. Anterior 

 antennae in female distinctly 4-articulate ; posterior antennae about as in Anchorabolus. 

 Oral parts resembling in structure those ist the said genus ; posterior maxil- 

 lipeds. however, less slender. 1st pair of legs of nearly the same structure 

 as the 3 succeeding ones, inner rainus in all pairs very small and rudimentary, 

 uniarticulate. Last pair of legs without any inner expansion of the proximal 

 joint, digitiform process of this joint very slender and elongated. 



Remarks. This new genus differs very conspicuously from Anchorabolus, 

 both as regards the armature of the body and the structure of some of the ap- 

 pendages; yet it exhibits an unmistakable general affinity to that genus, so that 

 it ought undoubtedly to be included in the same family. 



205. Echinopsyllus Normani, G. 0. Sars, n. sp. 



(PI. CCXII). 



Specific Characters. Female. Body comparatively slender, rapidly tapering 

 behind, with the segments sharply defined. Cephalic segment rather large, fully 

 as long as the 3 succeeding segments combined, and produced on each side in 2 

 successive acuminate processes of considerable size and pointing straight outwards, 

 antero-lateral corners conically produced, as in Anchorabolus; dorsal face exhibiting
