harforcU in a manuscript note of the author. He considers that the 

 specimens belong to the genus Cirolana, or a closely allied type, without

 Miers, .Efja harfordi is probably a Cirolana. lie had not seen Lock- 

 ington's description, but followed Miers regarding the systematic posi- 

 tion of the species. 



Specimens of 2Ega harfordi were sent by Mr. S. J. Holmes to the 

 National Museum from the California Academy of Sciences, which 

 prove to be identical with Cirolana calif ornica Hansen. 



5. CIROLANA LINGUIFRONS, new species. 



Color, yellow, marked with scattered black dots. Body elongate- 

 ovate, about live times longer than broad, greatly convex. 



Head with the frontal margin i)roduced in a long, straight proc- 

 ess, rounded anteriorly and somewhat dilated. 

 Eyes large, distinct. First pair of antenna' with 

 joints of the peduncle large; Hagellum of fifteen 

 short joints extends to the posterior margin of 

 the third thoracic segment. Second pair of an- 

 tenna', with a tlagellum of thirteen long joints, 

 extend to the posterior margin of the fifth thoracic 

 segment. 



The first three segments of the thorax are short; 

 the other four segments are long. The epimera of 

 the second, third, and fourtli segments are not pro- 

 duced at the apex; those of the fifth, sixth, and 

 seventh but slightly produced. 



All the abilominal segments conspicuous, the 

 first five being of equal length. The terminal seg- 

 ment is rounded i)osteriorly, faintly crenulate and 

 fringed with long hairs. The base of this segment 

 is raised above the other portion and has a well- 

 defined edge with two points extending backward, 

 one on either side of the median line. The uropoda 

 extend beyond the tip of the abdomen; the inner 

 bran(;h is obliquely truncate; the outer branch is more rounded; both 

 branches are fringed with long hairs. 



The prehensile legs are short; the gressorial legs are long and slender. 

 The legs increase gradually in length from the first to the seventh ])air.
