OENEKAL RKMAKKS. 



I coiLsider tliis ;i subspecies of SpargnnophUuti Bmiluinu, al least until a closer 

 investigation of better material may reveal otlier characters, if any there are. Spnr- 

 ganophilus gnatemalensis is one of tlie smaller species about 10 cm. long by 2 mm. 

 wide; the specimens were considerably stretched. Color is deep flesh, with an intense 

 deep, dark violet lustre, much darker than in any other species and woll prcscrvcil in 

 alcohol, in which the specimens appear blackish violet. 



Setre are lateral and dorsal. 



flitellum extends from xvi-xxvi, but cannot be well defined on the ventral 

 side. The tnhercu/a [tnhertdtix arc in the shape of two parallel ridges extending from 

 xviii to xxii or specimens from Fatal and (,'oban, wiiich I take to belong to the .same 

 species as those from Los Bancs in the City of Guatemala. 



INTERNAL CHARACTERS. 



Of these T could only distinguish a few. The xpermnfhecff: are in three pairs, 

 one each in vii, viii, ix, opening in the anterior intersegmental groove. The apical 

 L'lid ill the fully developed spermatheca is very wide, flattened like a mason's trowel. 

 Several of the sperraathecie possessed a slit or opening in the npical end whicli cora- 

 tnunicated with a longer or shorter .sac, continuous with the exterior lining of the rest 

 of the spermatheca. It is possible that this is only a result of maceration, as I have 

 seen nothing like it in other species of Sparganophilus, and it is not probable that we 

 here have an analogy with the spermathecae of Enchytrreus or Sutroa, where this 

 organ communicates with the intestine. 



/'rtiKtiid's are found in four pairs and situated in somites xxiv-xxvii or one 

 somite further back than in >'ip. Be/i/irnni. Tiiis in specimens from 8apote. If this 

 character holds good it is one of considerable importance. 



Hearts were in viii, ix, x, xi strongly developed, but mit filling the cijelom. 

 Rome of the Guatemala Sparganophili possessed only three pair of hearts in somites 

 ix, x, xi, with the ventral vessel branching in xv/xvi. Those were specimens from 

 Los Arcos. Others again from Amatitlan pos,sessed the hearts in x, xi, xii, .xiii, with 

 the ventral vessel divided in xv/xvi, while those from Los Bafios, Guatemala City, hail 

 the ventral vessel branched in xiv/xv. I believe those from Amatitlan and Los 

 Arcos belong to different species, but, as all the specimens are lost, I can only call 

 attention to the differences and to the importance of further investigations. 



Sparganophilus carneus n. su))sp. 



Habitat. Mississippi river near Clayton, Iowa, in soil at the water's edge, 

 under pieces of boards and lumber. Numerous specimens at end of .Vugust, ISUO, 

 only few of which were adult'. 



Oencrnl remark!^. It is [)robable that this is only a iinrtlieiii fni-m nf Sparga- 

 nophilus Benhami, from which species it differs principullv in llie form i>f the sperm- 

 atheca', and l)y a much lighter color. The specimens at my eomniand were not in projier 

 condition and the shape and jxtsition of the tnbereula pubertatis cnuM not lie made out.
