S. I. Smith — Crustaceans of the Atlantic Coast. 88 



The number of dorsal aculei upon the telson varies from four to 

 ten pairs. The greatest number noticed being in the case of two 

 females 48 and 49""" in length, from the coast of Norway ; the small- 

 est number, in males 27 to 35""" long and females 31 to 34™"', from 

 our own coast. That the number has no very close relation to the 

 size of the individual is shown by a male 34""" long having six aculei 

 on one side and eight upon the other ; while the largest specimen 

 examined, a female 56"'"' long, from the Bay of Fuiidy, has four upon 

 one side and five upon the other. In thirty specimens from New 

 England, Nova Scotia and the coast of Norway, the terminal spines 

 of the telson are as described by Kroyer, that is four median ciliated 

 ones and two stouter each side, making eight in all. A single female 

 specimen, 31""" long, from Labrador, differs however in having five 

 median ciliated spines with two stouter spines each side, making nine 

 in all, — a case precisely similar to that mentioned under H. Gaimardii . 



The following notes on the color while living were made by Pro- 

 fessor Verrill on an adult female, from 12 fathoms, Johnson's Bay, 

 Bay of Fundy, 1870. Body pale flesh-color, beautifully spotted and 

 barred transversely with orange-brown, the abdomen with somewhat 

 rounded, unequal spots which tend to form transverse bars above, 

 but on the second, third and fourth segments there is a regular band 

 of this color. The carapax is spotted on the sides with orange-red 

 and sparingly with sulphur-yellow; the upper portion bluish green, 

 finely specked with brown and yellow, and with three lateral spots 

 on each side and two median of bright blue. Between the eyes 

 and passing obliquely backward is a stripe of red. On the sides of 

 the abdomen are five specks of sulphur-yellow and above these are 

 two small bright blue spots on the fifth segment and a median one 

 with two smaller each side on the second. The telson and uropodal 

 lamella! are brownish at base, behind which there is a sulphui'-yellow 

 band bordered with white, the rest of the lamella si^eckled with 

 brown, and the outer ones with a semi-circular spot of dark purplish 

 brown near the middle of the outer margin. The flagella of the 

 antennae are salmon-color banded with orange-red. The first pair of 

 cephalothoracic legs are red at base and on the terminal segments ; 

 the second are banded with red near the base and at the tip ; the 

 third and fouith are red at base, then banded with yellow, whitish 

 and dark brown alternately, and the terminal segments flesh-color ; 

 the posterior pair are similar but have a sulphur-yellow base. The 

 abdominal legs are flesh-color, spotted and transversely banded with 

 dark red and sulphur-yellow.
