p. 67, and in two pajiers in tliis stM-ies (Brade-Biiks, ]\Iai-. 

 191i) ami li»19 h), it will be soeii that the name at the head 

 of this paragraph has priority, and that the spelling of the 

 •reneric name is as there shown. 



Blaniulus guttulatus (Bosc, 1792). 



The writer is in agreement with Chamberlin in his use of 

 this name, but lulus pulchellus, Leacli, 1814, is a synonym. 



Nopoiulus mnnitus (Brandt, 184]) = yopoiulus lochi 

 (Gervais, IHil) =JSopou>lus venustus (Meinert, 18G8). 



Under the name Nopoiulus pulchllus (Leach) it is evident 

 that Chaniberlin refers to the form called JS. kocJii (Gervais) 

 in the eighteenth pai)er in this series (Brade-Birks, Oct. 1919), 

 l)Ut lulus pulchellus. Leach, 1814, has been shown to be 

 synonymous with luhis guttvlatus, Bosc, 1792 ; and, though 

 the name lulus pulchellus, C. L. Koch, 1838, has been used 

 for the animal of which we are now speaking, that name, 

 being preoccupied by Leach's, use of it, cannot stand here. 

 We fell back upon the name kochi [lulus koc/iii, Gervais, 

 18-47), but, accepting Chamberlin's synonymy, we must adopt 

 an earlier name, and call the animal Nopoiulus mtnutus 

 (Brandt) [lulus 7ni7iu(us, Brandt, 1841, Recueil. p. 89). 



Further Considerations. 



Biolemann (1921), giving a diagnostic key, expressly 

 mentions the family Blaniulida^ in his title. As far back as 

 1847 C. L. Koch (Syst. d. Myr. p. 48) speaks of " Blani- 

 uliden," and as this name antedates even the genus Isolates, 

 Menge, 1851, the present writer feels that the name Blani- 

 iilidee is to be preferred to Isobatida3, which is used by C/liain- 

 berlin (1921). As Chaniberlin says, "Tiieuseof Protoiulidas 

 for this family is inadmissible both because it is antedated by 

 the names Isobatidaj and lilaniulidre and also because it is 

 not based upon an included genus." 



New genera are established l)y Biolemann (1921), and as 

 13ritish forms fall into three of them, a list of the species thus 

 affected is aj)pended : —
