J. H. ORTON. 
This one incomplete, but with an internal process on the right heemal 
process. The arch of the vertebra anterior to it is complete. 
7th vertebra from posterior end has two pairs of heemal and neural 
spines, is longer than normal and apparently equal to two fused 
vertebree. It is counted, however, as one. 
4th, 5th, and 6th vertebree from posterior end have been broken and 
recovered at some period of life of the fish. 
The last vertebra bears three pairs of neural and two pairs of hemal 
spines, it is nearly twice as long as a normal one, and has a thickening 
in the middle of the centrum where apparently two vertebre have 
fused. It is undoubtedly two vertebree fused. It is, however, only 
counted as one in the table. 
* 3rd complete arch has a tiny extra connecting hzemal process on the 
left. 
* Middle tips of hzemal arches with curious concretionary appearance, 
just as though the arches were of metal and had been melted in parts. 
The right heemal process of 28th vertebra is joined to junction of heemal 
processes of 27th vertebra ; the left process of the 28th vertebra being 
free. 
13th vertebra from anterior end is about half as long again as normal, 
and has ridges around its middle indicating fusion of two vertebree. 
It is, however, counted as one. 
There is no normal articulation in the middle, but complete fusion. 
* Oth vertebra very long and apparently two vertebrae fused, similar to 
704. It is counted, however, as one. 
* It is quite possible that one or more arches are missing here ; possibly 
too well cleaned. 
Arch incomplete, though the one anterior to it is complete (broken, but 
still attached to centrum). 
Ist hemal arch broken, but still attached to vertebra. 
There is nothing unusual in the appearance of this skeleton. 
Ist heemal arch with a rib attached. 
2nd, 3rd, 4th, 5th, and 6th rays of anal fin anastomising. 
In the region two-thirds from anterior end the hzmal and neural arches 
arise from abnormal positions and there are a few extra spines. 
Several hzemal arches with processes interchanged, 1.e. processes on oppo- 
site sides not joined up with fellow, but with those anterior or 
posterior to them. 
3rd hemal arch broken, but was undoubtedly complete. 
46th vertebra from anterior end, 3 pairs of hemal and 23 pairs of 
neural spines. The centrum is abnormally long, nearly twice normal 
length, and is apparently equal to at least 2 vertebree fused. It is 
counted as one.
