Mii.i'llJiinj fcetli. — 'IMie type has twenty-one maxillai-y teetli and not 

 tweTity, as stated h\ Oufilby. The anteriof one is veiy small, tlie second 

 a little lai'fifer, while the third and onwards to the twenty-first might 

 almost be termed subequal in lenotli, but a few of the posterior ones arc 

 stouter than the anterior, this being a.cliaracter of DeinJrop/iif. 



Vtuii'hrnl !'<-iilt'.<. — These scales are slightly enlarged as in I 'I'lnlnij'/ii^.

Jinthi fruh'K. — 111 tlie original description, tliose measurements whicli 

 relate to the scaling, are the totals of the smallest and largest numbers, 

 and for convenience I ha,A'e recounted those of the tyfie, which are as 

 follows: — Scales in 13 rows. Ventrals 1H7. Siib-caudals 116. Anal 

 divided. 



Tfiiijiaruh. — These shields are different on the two sides of tlie head ; 

 on the riglit side there are two upper and three lower, the upper anterior 

 being as long as the first and secrond lower-, while on the left side there ai'e 

 three pairs of shields. 



Ijiih'niU mill L'Jiiii shield!'. — On the left side of the ja<w there are five 

 lower labials in contact with the anterior chin shield, the fifth just 

 touching it, while there are only four labials in contact with the corres- 

 ponding chin shield on the right side. The fifth is the largest, and the 

 total imnibci- on each side is nine. 



There are eight upper labials, and the fourth and tiftli enter the eye. 

 The posteiior chin shields aie much longer and narrower tlian the anterit)!', 

 wliile the I'ight anterioi' is divided fnto two in the type. 



Aftiiiitiex. — The characters of Ogilby's species are, in many cases, 

 intermediate between those of iK ntUitjaxtpr ajid D. jiii)i('t-iil<ifHs",Hs will l)e 

 seen by the description, but those of the type are closer to the former 

 species, nndei' which name J have placed it.

lionneberg and Andersson remaik on two specimens in their 

 possession, which are in many characters intermediate between D. puiicfii- 

 Jdtim and D. callitjuxter, atid they doubt whether the two species should 

 remain distinct. I am inclined to agree with them, and hope at a later 

 date to be able to rrn moi-e fulh- into the question, and supplv data that 

 will either prove or disnidve the \ali(lit\ of the laitt-r sjiccics, or will 

 enable moi'e expei'ienced workers to cairv on the investigations to 

 finalit V.
