Scutum antice carinalum atque dentatum. Rostrum horizontale, ad 

 apicem aliquantum resimum, longitudinc oculos bis superans, 

 squamam antennamm extcriorum quarta parte a?quare deficiens. 

 Denies marginis superioris septem (rarius octo) ejusdem mngnitu- 

 dinis eodemque intervallo inter se separati, horum unus (rarius 

 duo) in carina scuti positus : marginis inferioris unus prope apicem 

 positus. Margo scuti anterior uno aculeorum pare. armata infra 

 oculos posito. Telson duo minuta aculeorum paria gerens. An- 

 tenna interna? apicem squamce extcriorum longe superantes. Pecks 

 primi prater apicem squamce antennarum multo extendentes, 

 antennarumque interiorum longitudinem assequentes; dactyli 

 pedum primi atque secundi parium clongati. Carpus secundi 

 paris biarticulatus. Long. | unc. 



Rostrum moderately long, and very elegant from the fact of 

 its being doubly bent ; in the middle it inclines slightly down- 

 wards, and at the apex it again bends upwards. There are seven 

 or eight equidistant and equal-sized teeth above, of which not 

 more than two are situated posteriorly to the orbit; the apex is 

 simple and bent upwards ; the single tooth below is placed near 

 the apex of the rostrum and opposite to the last tooth of the 

 upper side. On either side of the carapace, below the orbit, is a 

 single tooth. The interior antennse arc long, and considerably 

 exceed the antennal scales in length. Two pairs of spines on the 

 telson. The first feet are long, and, when directed forwards, 

 project beyond the antennal scale by the length of the lingers, 

 which in both the first and second pairs of feet are much larger 

 than in the genus Hippolyte, elongated and curved. Colour 

 reddish. Length, from the apex of the antennal scales to the 

 end of the telson, ^ inch. 



I took two specimens of Doryphorus Gordoni in Lamlash Bay 

 in 1853, and afterwards found it among some Crustacea sent to 

 me from the Moray Firth by Mr. Edward — the same locality 

 from whence Mr. Spcnce Bate subsequently described the spe- 

 cies. The absence of any prolongation in the third segment of 

 the abdomen, the large size of the first pair of feet, the elongated 

 hands of the first two pairs, and the greater length of the first, 

 third, fourth, and fifth pairs, as compared with the second, seem 

 to afford ample grounds for raising this interesting species to 

 generic rank; and I had already drawn up the characters of the 

 genus in MS. when Mr. Spcnce Bate's description appeared in 

 the ' Natural History Review/
